Mitt Romney is quickly becoming the frontrunner in the race for the GOP's 2012 presidential nomination. But, is he reaching the top of his level of support from primary voters?
Jed Lewison at Daily Kos says that may be what's happening.
In the Des Moines Register's new poll of Iowa's GOP caucus goers, just 10% say Romney is their second choice, compared with 18% for Bachmann and 12% for both Tim Pawlenty and Ron Paul.
In order to win the nomination, candidates must be able to win over supporters from former rivals who have either dropped out or become irrelevant. So far, Mitt Romney hasn't shown an ability to that. It appears there may be a ceiling to his support—the Mitt Romney ceiling. And if there is, he's in a real trouble.
The second-choice numbers in this poll reflect a pattern. Last week, PPP released a poll showing most Palin supporters would vote for Herman Cain or Michele Bachmann if she doesn't run. Romney picked up just 12% of those voters.
