Yes, they do.
But don't you think that an Ultra American group like the Tea Party should use American made cars?
Or are they trying to make some kind of stupid point by not using American made cars and thereby not supporting Unions? If that's the case, they missed the point entirely because German autoworkers are even more Unionized than our own.
If indeed the Tea Party is "Ultra American," then that would mean that the owner should be able to drive whatever-the-fuck he wants to drive, and paint it, without worrying about a fucking political constituancy, the French, or wing-nut editors from the NYT.
