In the poll, Mike Huckabee and Mitt Romney paced the GOP field at 19% and 18%, respectively. Newt Gingrich took third at 13%, followed by Palin (12%), Trump (8%), and Ron Paul (8%.)
That's a stunning turnaround from one month ago, when Trump led PPP's national survey with 26% to Huckabee's 17%.
But since then, Trump has taken a beating in the media. NBC questioned Trump about his his failed business ventures and bankruptcies -- questions which Trump brushed off by saying he was paid millions, "for his genius."
Also perhaps contributing to Trump's sudden downfall is the fact that the birther population, a group Trump heavily courted by insisting that Obama release his long form birth certificate, was cut in half once Obama released that documentation.
The PPP poll was conducted May 5-8 among 610 Republican registered voters nationwide. It has a margin of error of 4.0%.
