Possible Third Party Runs are Catnip

First Lou Dobbs opened the door to a third party presidential run in 2012. Now Sarah Palin is dropping hints. How much of the Republican nominee's share of the electorate is going to be devoured by extraneous teabagger campaigns? Still, I don't know if I buy the assumption that the Republicans will not nominate Sarah Palin. Sure the establishment of the party, at least the McCain campaign insiders, hates her like poison, but the neocons, Rush Limbaugh, hard right evangelicals and the NRA-types all adore her. If not Sarah Palin, then who?
