What are the alternatives? If Obama wins, he will solidify the detest for the left and the radical left in ways that he hasn’t managed to accomplish yet. Guns are flying off shelves and carry permits are through the roof. States are starting to exempt themselves from Obamacare and otherwise take steps to assert sovereignty, and the next election after that the left will be destroyed and furthermore, the Republican party will learn that it has to do better than select Massachusetts RINOs; perhaps some real tea-partier will be the next nominee, and Republicans will probably have a few solid terms in its future. On the other hand, if Romney wins, the Republican central committee will think that RINOs are just fine, select another one, and probably Hillary! will win after that, and maybe again. And then Chelsea! On the other hand there is the small issue of the Supreme Court, and giving away national security secrets, and squandering the treasury on LGBT renewable energy company boondoggles. It’s not obvious to me who would be worse, long-term, for the country if it got down to Mittens vs. The Obamanation. Both have grave consequences.
The place to fight that battle is in primaries, and in getting ready for primaries. What appeared to us this past spring was a disorganized herd of cats. Santorum's "tastes great!" vs. Gingrich's "less filling!" served as sad excuses for discourse.
