POLLSTER AND PROFESSOR HAMID GHANY
The poll was conducted from Thursday, April 10, to Sunday, April 13, 2025. A total of 1,650 questionnaires were administered in Trinidad over 11 constituencies that were selected based on a marginality formula that I invented in 2002. The margin of error for the Trinidad poll is +/- 2.5 per cent.
A total of 530 questionnaires were administered in Tobago—265 questionnaires in Tobago East and 265 questionnaires in Tobago West. The margin of error for the Tobago poll is +/- 4.0 per cent.
Calculation of marginality in Trinidad
In conducting the national survey, it was decided to use the parliamentary electoral constituencies as a natural geographical basis for gathering the data. To this end, the official results of the general elections of August 10, 2020, provided the basis for the choice of constituencies together with the boundary and constituency changes contained in the Report of the Elections and Boundaries Commission dated March 13, 2024, together with my marginality formula.
A calculation of marginality (M) was made to confirm what were the projected marginal constituencies for the 2025 general election. The symbols for this formula are M for marginality, and D for the midpoint spread of the deposit level for the largest (L) and smallest (S) constituencies if everyone were to vote.
This formula applies to electoral systems that use the first-past-the-post method where the retention of the deposit of every candidate is calculated at one-eighth of the total votes cast in a constituency. The deposit is a fundamental statistical benchmark and can serve as a guide to determine where a survey should be conducted if marginality is the key element in the search for truly mixed political opinions because in marginal constituencies the first and second candidates will normally save their deposits because marginality always tends to move closer to zero as the difference between the first and second candidates.
The constituencies with the largest electorate (L) and the smallest electorate (S) must be divided by 8, and then their difference divided by 2, in order to calculate D. Therefore, the formula is: (L/8 – S/8) / 2 = D
Once D is determined, then the statistical formula for calculating the outer limit of marginality (M) is: {(L/8) – D = (S/8) + D} = M
As a consequence, the following constituencies in Trinidad can be considered marginal in relation to the 2025 general election, owing to the fact that their projected marginality (calculated difference measured between the first and the second candidates based on 2020 electoral data and 2024 boundary changes) fell inside of > 3,504:
1. Aranguez/St Joseph (823)
2. Barataria / San Juan (1,060)
3. Moruga/Tableland (1,072)
4. Chaguanas East (1,086)
5. San Fernando West (1,618)
6. Claxton Bay (1,813)
7. Tunapuna (1,927)
8. La Horquetta/Talparo (1,939)
9. Toco/Sangre Grande (2,976)
10. Cumuto/Manzanilla (3,326)
11. Mayaro (3,364)
These constituencies were polled by using three PDs per constituency on the basis of choosing one very strong PNM PD from 2020, one very strong UNC PD from 2020 and one marginal PD from 2020 at 50 questionnaires per PD.
ANALYSIS
Political party support
The performance of the PNM Government over the last ten years, which is essentially connected to the legacy of the former Prime Minister, Dr Keith Rowley, has placed the new Prime Minister, Stuart Young, at a disadvantage, as he has to either acknowledge that he was part of this performance or he is going to distance himself from it.
The Leader of the Opposition, Kamla Persad-Bissessar, has rebranded herself as the leader of a new coalition of interests which has broadened the base of the UNC by bringing personalities who were previously opposed to her into her fold just as they have changed their disposition towards her.
The opinion poll respondents have taken a somewhat positive view (45 per cent) of the UNC coalition of interests, while the PNM has not been as favourably viewed by respondents in the poll (30 per cent).
The split-vote phenomenon is alive and well, as the combined effect of the support for the Patriotic Front (7 per cent) and the National Transformation Alliance (6 per cent) has a 13 per cent voter deviation looming over the heads of both the UNC and the PNM.
As regards which of the two major parties they are hurting more, it is difficult to tell. If it is the UNC Coalition, then that would mean that they would have to make further inroads into the UNC Coalition to hurt their chances. If, however, they are hurting the PNM as part of an anti-UNC vote, then the UNC will be the prime beneficiary of such a vote split.
This outcome was gathered from 11 marginal constituencies, and a 13 per cent vote split will be significant under the first-past-the-post system of election. If the PF and the NTA are cutting into UNC coalition votes, then more cutting will be required to reduce the chances of the UNC coalition. If the PF and the NTA are cutting into PNM votes, then that does not augur well for the PNM.
How the actual vote splitting will play out in any of these marginal constituencies cannot be predicted, but any close finishes could be the result of vote splitting one way or another.
This poll was taken two weeks before the General Election and so the snapshot may change if there are any switches among third party votes as a result of the final two weeks of campaigning.
Believability/Good for the Economy Questions
The Believability/Good for the Economy questions showed that the Leader of the Opposition enjoyed a lead over the new Prime Minister that was consistent with the choice of party in the final question of the survey. The separation of these questions between the start of the poll and the end of the poll was designed to see whether there would be a modicum of consistency between these first responses and the last response.
Essentially, there is a correlation between them. However, in a first-past-the-post system, one does not know how the final results will play out in individual marginal constituencies.
The responses to these questions may be indicative of respondents seeking a change now that Dr Rowley is gone, and they may not be responding as positively to Prime Minister Young as his replacement.
On the flip side, the Leader of the Opposition, Kamla Persad-Bissessar, has formed new alliances which may have been viewed positively by the respondents as a new image that they may be willing to try.
TOBAGO
The two Tobago constituencies were polled using five PDs in each constituency based on trending results using 2020 general election data and tracking those PDs through the January 2021 and December 2021 Tobago House of Assembly (THA) results.
The tracking of these results for the initial PDs from 2020 through the two THA elections of 2021 was deemed to be necessary seeing that (i) the PNM lost ground, (ii) the PDP gained ground, and (iii) the TPP was subsequently formed out of the PDP. Geographical spread was also a factor in selecting PDs.
The methodology had to contend with the effect of the decline of the PNM in three elections (2020 General Election, January 2021 THA elections and December 2021 THA elections) and whether they would regain any lost support because of the split between the PDP and the TPP. At the same time, there was the need to measure whether the PDP would hold its 2021 vote levels or whether the TPP had inherited the votes of the PDP after the split between them in 2022/2023.
ANALYSIS
Political Party Support
The likelihood of split voting is very apparent in Tobago given the percentage differences between the three main parties in the contest on the island. The PNM is leading with 47 per cent; however, the TPP, which was formed out of the PDP, is at 32 per cent and the PDP is at 9 per cent. There was also 4 per cent of respondents who insisted to the field data-gatherers that they were keeping their choices private and did not want to share that information. Also, 3 per cent of the respondents did not know. That cumulative 7 per cent remains an unknown factor, while 4 per cent of the survey said that they would be voting for other parties/candidates.
In a tight race where up to 20 per cent of the survey is not clearly identified with either of the main parties (PNM or TPP), the two seats in Tobago could go the way of the PNM if the vote-splitting continues to trend in favour of the PNM. Only one per cent said that they would not support any of the parties contesting the race.
As regards which of the two major parties is hurting more as a consequence of this split-vote phenomenon, it appears that the TPP is more likely to be affected by the loss of votes to the PDP since it is the party out of which the TPP emerged.
The Believability Question
The Believability question showed that the new Prime Minister enjoyed a lead over the Chief Secretary of the THA which was consistent with the results for the PNM on the question of choice of party.
However, the Chief Secretary (36 per cent) scored higher than his party (the TPP) did in the question of choice of party, which was 32 per cent. Interestingly, 8 per cent said that they did not know, 9 per cent said neither of them and 1 per cent said Watson Duke.
The responses to these questions may be indicative of respondents seeking a change now that Dr Rowley is gone, and they may be open to giving the new Prime Minister, Stuart Young, a chance as his replacement.
On the flip side, the Chief Secretary has survived the split in the PDP, and his administration in the THA has remained intact during the transition from being independent members of the THA to becoming members of the TPP that was formed in 2023. There has been a lot of controversial commentary between himself and the former prime minister as well as the leader of his former party, the PDP. Such controversial commentary does take a toll on public imaging, and, although he is not on the ballot, his party—the TPP—certainly is.
Conclusion
This general election is likely to be affected in marginal constituencies in Trinidad and the two Tobago constituencies by split voting involving third parties. In any close contests in these constituencies the pendulum could swing one way or the other because the quantum for third parties, others, not sure and private views takes the figures into double digits.
Any late swing in the final two weeks of the campaign after this survey was done could either exacerbate the vote split or reduce its impact. So far, it appears to be a factor.
