SEN. Grace Poe emerged as the top choice among potential presidientail candidates in 2016 in the latest surveys conducted by Pulse Asia and the Social Weather Stations (SWS).

In the SWS June 5 to 8 poll, Poe has a rating of 42 percent, an 11-percentage point increase from the 31 percent of respondents that picked her in March.

Poe also topped the Pulse Asia survey with a rating of 30 percent.

So where's Vice President Jejomar Binay now? Binay, who used to top the surveys of presidential wannabes, has become the second choice, whose ratings dropped from 36 percent in March to 34 percent in June in the SWS poll.

The Pulse Asia polls showed Poe has overtaken Binay, earning 30 percent compared to the Veep's 22 percent.

Remember Poe and Binay were both adopted children. But only Poe was a "foundling."

And only Binay was relentlessly attacked for alleged graft and amassing unexplained wealth.

Interior Secretary Mar Roxas, the presumptive Liberal Party standard-bearer, was third in the SWS survey, with 21 percent from 15 percent in March.

Davao City Mayor Rodrigo Duterte, who said he might run for president if he overtakes Binay in the polls, placed fourth in the survey with 20 percent, up from 15 percent in March.

If Binay's ratings in the polls continues to fall, Duterte might run for president.

President Noynoy Aquino remained mum on his anointed successor who will be expected to continue his "matuwid na daan" (straight path) reforms.

It now looks like Secretary Mar Roxas would pair with Sen. Poe. But if the ratings are any indication, Roxas could again slide as Poe's vice presidential bet as he did to PNoy.

Who knows he would win as Veep?

If by any chance Poe gets disqualified on citizenship issues, this could be Mar Roxas' fattest chance to become the country's president.
