Even considering the Rasmussen poll of 750 likely voters dated Dec 13th, Real Clear Politics still shows Newt leading with the average of all polls at 27.2% to Romney's 18%. For entire avgs:Gingrich is ahead in most polls but I doubt he will be able to hold it. As boring as he is, I don't think I would count Romney out only because he has deep pockets and hasn't really tapped much of it yet.
Have to admit, I like the Obama-Lite comparison.
RealClearPolitics - Election 2012 - Iowa Republican Presidential Caucus
As pointed out by several of the pundits, Romney has his core followers that comprise between 18-25% and never seems to break that ceiling. The rest of the voters are Not-Romney and have bounced from Perry to Cain to Newt, and now some seem to be drifting over to Paul. The debate tonight should be interesting, and I can't help but wonder if anyone will bring up the assault on Newt by the GOP elites and inside-the-beltway establishment. These are the same puppet masters that gave us Bob Dole and John McCain - mushy moderates that turned out to be two of the most uninspiring candidates in history.
Mitt Romney would fit right in with them, and could possibly yield the same results in spite of getting to run against the weakest president with the worst record ever; all Romney would need to do to lose is try to appeal to the moderates and independents in an effort to be Obama-light. The political pendulum has swung past that point as proven by the 2010 mid term elections. The American public has seen that socialism won't work, so now they're looking for the anti-Obama - and that's not Mitt Romney.
