David Frum, GOP speechwriter, is one of those rare reasonable Republicans.  He hates the Tea Party and the extreme turn to the crazy right that his party has taken.

Today he endorsed Mitt Romney, with some bizarre reasoning:

The congressional Republicans have shown themselves a destructive and irrational force in American politics. But we won't reform the congressional GOP by re-electing President Obama. If anything, an Obama re-election will not only aggravate the extremism of the congressional GOP, but also empower them: an Obama re-election raises the odds in favor of big sixth-year sweep for the congressional GOP – and very possibly a seventh-year impeachment. A Romney election will at least discourage the congressional GOP from deliberately pushing the US into recession in 2013. Added bonus: a Romney presidency likely means that the congressional GOP will lose seats in 2014, as they deserve.

Translation:  If Obama wins, congressional Republicans will go completely ape and destroy the country. They will deliberately tank the economy and then impeach the president. Therefore, to avoid this, we have to kick Obama out of office.

Better translation:  Give the terrorists what they want.
