They Live

Yes, the Tea Party is still around:

In researching her recent book, "The Tea Party and the Remaking of Republican Conservatism," Harvard professor Theda Skocpol found that about 1,000 local tea party groups formed in 2009-2010. Today, she estimates there are about 600. A declining number, yes, but still what Skocpol, an expert on civic engagement, calls "a very good survival rate."

"They're not dressing up and going to demonstrations in the street. They're meeting. They're poring over the legislative records of these Republicans that they've elected. They're contacting their representatives, and they're keeping the pressure on. They're following the debates, and they're going and they're voting.

"They're determined," she says, "and they haven't gone away."

If Orrin Hatch's reaction is any indication, they're going to be around for a while yet...
