Here's a positive, if somewhat predictable, development:
Trump's support has gone from 26 percent among GOP voters--putting him at the top of the field--to 8 percent, a tie for fifth place, in the span of a month. Public Policy Polling finds that Trump now has a 53 percent disapproval rating among Republicans. The birther issue that sent him soaring to such great heights is what was his downfall: In February, 51 percent of Republican primary voters thought President Obama was born abroad; now just 34 percent think so. And among those die-hard birthers, Trump gets only 9 percent of their vote, putting him in fifth place. With Trump out of the race, Mitt Romney regains his lead, with 21 percent of the vote, followed closely by Mike Huckabee, with 20 percent.
