I mentioned this earlier this week, but Karl Rove is preparing to drum the Teabaggers out of the Republican Party.

The resulting battle would pit two well-funded factions of the conservative base against one another in a set of expensive primaries that could drain resources, produce weakened nominees and set back the GOP’s chances to retake the Senate and protect its House majority. And it would further complicate already tricky efforts to carefully reposition the GOP on hot-button issues like immigration, gun control and fiscal policy.

The way I see it, Democrats win either way: If Rove wins, moderates might be able to join the Republican Party again, which means Democrats in Congress might be able to coerce some of them to their side on certain votes. If the Tea Party wins, the Republican Party will keep getting more and more unreasonable until nobody in their right mind would vote for them. But who should I bet on?
