triple whammy for Poe, Roxas & Binay in latest SWS survey, Roxas gains the most

Apparently there is a second survey for the presidentiables from SWS and this one puts presidenitables Grace Poe, Jejomar Binay and Mar Roxas practically on a there-way tie.

The survey was conducted Septemebr 2 to 5, 2105 and has the following ratings for the three presidentiables :

• Grace Poe : 26%
• Jemomar Binay : 24% (difference vs Poe – 2% points) 
• Mar Roxas : 20% (dofference vs Binay – 4% points)

(source : http://www.rappler.com/nation/politics/elections/2016/106788-sws-survey-breakdown-presidential-tie)

With a margin of error at +/- 3%, Poe and Binay are on a statistical tie while  Roxas  vs Binay with a difference of 4% points is statistically significant but  it being just shy by 1% point, that is considered a statistical tie.

unlike the other SWS survey which was an options survey (respondents were asked to name 3 candidates who can replace Aquino), this is a real elections survey where respondents were asked to identify only 1 candidate who they might vote as president if the elections were held during the time of the survey.

this survey gave a triple whammy to all three presdientiables Poe, Binay and Roxas.

1st whammy – this is the biggest whammy and it is for the benefit of Mar Roxas. mar roxas before this survey was a far third to Poe and Binay. roxas jumping to tie the front runners is a big jump for roxas. this mimics the same kind of giant improvement that Roxas got in the other SWS survey where he got a +18% point improvement catapulting him to 2nd position (read here: http://wp.me/pnw03-1W0).

this shows Roxas is a legitimate contender in the election and is on an impressive increasing trend. the increasing trend will serve Roxas well as we move to the actual election in 2016, this means Roxas is building his support base at the same time the support base of Poe and Binay are not moving if not weakening.

2nd whammy – this one hurts Garce Poe. Poe in previous surveys showed she was way ahead of the others and was a clear leader. this survey with two of her rivals catching up with her shows she is not invincible. it says she can be beaten.

3rd whammy – this hurts Jejomar Binay. Binay used to be the runaway winner in the polls but his ratings have been suffering and was on a massive declining trend since the corruption and plunder charges have been exposed in the senate. Binay just getting  a tie with the two others means Binay has not arrested his declining trend and continue to suffer in the polls.

unless Binay changes things, like address the corruption and plunder charges against him, the declining trend will continue and his numbers will shrink significantly by election time. it is possible that the shrinkage will be big enough that the other leaders will overtake him.

Roxas’ ratings have gone up driven by the endorsement of President Aquino for his presidentiable run and Roxas’ declaring that he will continue Aquino’s “Daang Matuwid”. Aquino endorsed Roxas’ presidential run in an event held at Club Filipino on August 30, 2015. Roxas also ran ads almost the next day where he said he will continue Aquino’s “Dang Matuwid”.

Roxas has gained the momentum from this survey and will allow him to enlarge his support base.

Poe will need to work harder to get back her stellar number one position. Let us see if her numbers will improve on the next survey behind her announcement that she will run for president in an event that happened after this survey was conducted.

Question On Methodology & Design For SWS :

we noticed that the two presidentiables surveys, the options survey and this election survey were run on the same time period. did that mean the questions for the these two separate surveys were in one questionnaire and both were asked of the respondents in the same sitting?

if so, was there no order bias in their answers? 

i would think there would be order bias and one or both of the answers of the respondents will be affected by the other. it would be difficult to accept the survey results if there was order bias.
