What if Mitt Romney...

...wins the Republican nomination after all? (A quick glance at Intrade shows Rick Perry fading fast; and the odds that New Jersey Governor Chris Christie gets in are worse than Sarah Palin's.)

So what if the field is set and Romney is the GOP nominee? It's hard to imagine the base, i. e., the "tea party," getting enthusiastically behind ol' Mitt. Will the crazies stay home, or run a third party candidate in the general? If so, all they need is to win one or two percent of the vote in such swing states as Ohio and Florida to tip the election in President Obama's favor.
