Greg Ip thinks we’ve hit peak Tea Party. We’ve known for a while that the Tea Party hasn’t brought any new voters into the electorate. The rump base of the Republican Party has merely traded their elephant hats for tricorne hats with tea bags hanging off of them.
My guess is that we’re seeing some of the activist intensity in the GOP burning out. The tea people feel like they had a big win in 2010, and now they’re getting complacent just like Democratic activists did after 2008.
