2010 is shaping up to be the most entertaining midterm elections ever.
On the one hand, you've got the teabaggers howling for moderate Pub blood, and looking to repeat their stirring Pyrrhic defeat in NY-23 nationwide. The Club For Growth is already hunting bigger game, throwing their weight behind Marco Rubio in his Senate battle with Charlie Crist in Florida. Expect plenty more primary throwdowns, and third party candidacies when a heretical RINO survives their primary, to follow.
On the other hand, the left is having conniptions over the Stupak-Pitts Amendment to the House's health care reform bill, and there is a very strong likelihood that the Kossified grassroots will support some primary challengers of their own, or at the very least make life (and re-election) difficult for those that supported the amendment (or voted against health care reform, or both).
In other words, just the run-up to 2010 promises to see more than its share of electoral chaos.
