Blue Virginia has an interesting collection of Democratic comments on whether it's okay for a Democratic elected official to attend the Tea Party convention. Most say no.
During the 2007 debates, didn't Barack Obama say he would negotiate with Iran and other dictators without precondition?
So this is your Democratic talking point: Dictators, OK to talk to. Tea Party, Nah.
Democrats, you'd better learn to talk with the Tea Party. They're going to be running things in Washington in 2011.
