Handicapping of the 2012 presidential election is well underway: Obama vs. Huckabee. Obama vs. Romney. Obama vs. Palin. But what if Donald Trump were in the mix? The notion seems only slightly less outlandish after the Donald's splashy (and anything but humble) appearance at the Conservative Political Action Conference. And when we asked likely voters in the new NEWSWEEK/Daily Beast poll, we found that some of the GOP's biggest names would be wise to keep an eye out for Trump, who did surprisingly well. Could he play the Ross Perot wild-card role in 2012?
