“Should the Tea Party very begrudgingly mumble some kind of wet napkin support for Romney, or write off the White House and focus on Conservative House/Senate candidates to thwart the Executive Branch?”
None of the above. It should do what it should have done from the beginning: write off the useless and feckless gop and build a third major political party.
The irony here is thick, because the moment that Ron Paul walks and goes third party, the howling at FR will be at a fever pitch. After all, how DARE a Constitutionalist do anything but support the grand old plantation?! Why, it might even cause the mittens to lose! Oh, the horrors!
