IT’S A TIE
If elections held today: PP 34% — PNM 32% 
Story Created: Sep 20, 2014 at 10:10 PM ECT (T&T Express)As the race to general elections 2015 heats up, the results of a new poll show that if elections were called today it would be almost a dead heat between the ruling People’s Partnership Government and the Opposition People’s National Movement (PNM).
The poll-commissioned exclusively by the Trinidad Express Newspapers and conducted by data analysis firm Solution by Simulation (SBS)—indicates that political preference in the country are divided in near-equal numbers even though Prime Minister Kamla Persad-Bissessar remains popular as a leader.
The run-off factor could make a difference, the poll shows.
When presented with the option to return to vote for the PNM or the Partnership, the generic ballot shifts from a statistical tie to a lead for the Partnership.
But the poll also shows that the PNM has an edge over the Partnership in the marginal seats.
Following is the analysis of the poll by SBS:
SUMMARYWhile the countdown to the next general election has begun, the political preferences of the country remain deeply divided in near-equal numbers. A national poll of 678 adults who are eligible to vote revealed at least three main facts:
l Nationwide preference between the People’s National Movement (PNM) and the People’s Partnership (PP) remains statistically tied
l However, the PNM has more support in the key groups that decide elections: the marginal constituencies, voters of mixed ethnicity, and those who are unaligned or typically are not sufficiently motivated to vote for any party.
l The Prime Minister remains widely popular with a favourability rating of 46% and a job approval rating of 49%. The Opposition leader’s net favourability rating is +2%, returning to its 2012 level.
METHODOLOGYSolution by Simulation interviewed 678 adults in Trinidad and Tobago via a combination of live telephone calls and interactive voice response (IVR) from September 15th to September 18th. Telephone calls were placed to listed TSTT and Flow landlines in which at least one household member is registered to vote. Results collected through each mode were practically identical. The margin of error for the overall sample is +/- 3.8% and about 6% for the named subsamples. The poll was commissioned as exclusive research for the Express.
WHICH PARTY/COALITION LEADS NATIONALLY? …IT’S A TIEWhen voters are asked who they would support if a general election were held today (the so-called “generic ballot”), the result is a statistical tie. Of all respondents, 33.9% selected the People’s Partnership, and 31.9% selected the PNM. The Independent Liberal Party (ILP) and other parties combined for 8%, and 26% did not have a preference.
A statistical tie is a result that is so close that it is not possible to know which party is leading among the entire electorate of one million voters, from the survey of 678 voters. In this case the difference of 2% between the two major parties is well within the poll’s margin of error of 3.8%.
WHICH PARTY/COALITION IS WINNING?
…PROBABLY THE PNMThe national picture of a close election is more complicated when seat allocation is taken into consideration. While the PNM has a 17-point lead over the Partnership in its “safe” seats, and the Partnership is polling 23-points ahead over the PNM in its “safe” seats, the PNM enjoys a convincing 8-point edge over the PP in the marginal seats.
For the purpose of this analysis, the marginal constituencies are defined as the seats that changed hands between the 2007 and 2010 general elections; namely: Arima, Barataria/San Juan, D’Abadie/O’Meara, La Horquetta/Talparo, Lopinot/Bon Air West, San Fernando West, St Joseph, Tobago East, Tobago West, Toco/Sangre Grande and Tunapuna. The PNM’s lead of 8% in the marginal constituencies is above the margin of error for the sub-sample, meaning that we can say with statistical confidence that the PNM is leading in the composite of these seats.
Although the PNM enjoys this lead in these critical constituencies, the Partnership needs only to retain three of these 11 constituencies to maintain a 21-seat majority. Therefore, a precise estimate of the state of the election race requires further research into the marginal constituencies.
THE “RUN-OFF” FACTOR
…MAY MAKE THE DIFFERENCECurrently, the ILP and other parties are polling at a combined total of 8% of all voters, which represents 10% of all voters who expressed some preference. If this level of support is maintained, several “run-off” elections may be triggered in the closest marginal constituencies assuming that the proposed constitutional amendments are passed and acceded to by the President.
When presented with the option to return to vote for the Partnership or for the PNM in a hypothetical run-off only in the respondents’ constituency, the generic ballot shifts from a statistical tie, to a clear 5-point lead for the People’s Partnership.
Currently, the PNM is the preferred second-choice of third-party supporters: about one in three would return to vote for the PNM on the second ballot, about one in six for the Partnership, and the rest would not return to vote. However, this effect is neutralised by the number of PNM supporters declaring that they would not return to vote a second time. While 84% of Partnership voters say that they would return to vote in a run-off election, only 71% of PNM voters would.
In all, 38% of voters say that they would not return to vote in a run-off election—the majority of these persons are those who have no preference on the first ballot.
The marginal constituencies show a similar shift towards the Partnership in a run-off election. Within the marginal constituencies, the PNM’s eight-point lead in the first ballot drops to a statistical dead heat in a run-off. Counter-intuitively, the marginal constituencies reported the highest share of persons who will not return to vote a second time, with 42% saying that they would stay at home.
PARTY LEADER FAVOURABILITYPrime Minister Kamla Persad-Bissessar is polling strongly with a 46% favourability rating, while 38% rated her unfavourably. This gives her a +8% net favourabiliy rating. Opposition leader Dr Keith Rowley now has a 42% favourability rating, with 40% of persons rating him unfavourably; giving him a +2% net favourability rating.
However, the situation is reversed in the marginal constituencies, where the Opposition leader enjoys a +10% net favourability rating, and the Prime Minister a -2% net favourability rating.
This represents a decline from the +12% net favourability rating reported in the Express exclusive poll published on May 25-27, 2014. The Opposition Leader’s near-equal favourable/unfavourable numbers is a return to the situation found in the Express exclusive poll in May 2013.
PM APPROVAL RATING …STILL STRONGThe Prime Minister’s approval rating has remained steady from the May Express exclusive poll. Currently 49% approve of the job that she is doing as Prime Minister, with just 41% disapproval. Her approval rating is slightly higher than her favourability with the net approval and net favourability rating being equal.
HOW VOTERS EXPLAIN THEIR CHOICESMost respondents explained their preferences in one of four ways: assessment of a party’s record of performance, consideration of ethics and corruption, implementation of social programmes, and loyalty or tradition, in that order.
Most persons who cited performance as the deciding factor prefer the Government, while those who are most concerned about corruption or establishing ethical and transparent government prefer the opposition. Some of those who were interested in performance said that they would support any party who performed for the benefit of the country.
A significant number of persons want to support a party that implements policies to help them or vulnerable sectors of society, such as employment opportunities, pensions, healthcare, etc.
The largest group however were voters who could not or chose not to explain their choice, which accounted for about half of all respondents.
