This headlining act is surely to get tongues wagging. The National Tea Party Convention announced that it has booked Representative Michele Bachmann (R-MN) to speak at their February 2010 event in Nashville. This is probably enough to get Tea Partiers excited, but Bachmann isn't even the highlight of the show: Top billing will go to Sarah Palin, who will be the event’s keynote speaker. The convention is the first ever of its kind, and will be sponsored by Nashville-based Tea Party Nation. The conference will be a place for Tea Partiers to network and strategize for 2010.
