John Yoo believes that during wartime there's virtually no limit -- legal, constitutional, treaty or otherwise -- on a president's power. He can suspend the First Amendment. He can order the testicles of a small child crushed. It was his legal advice that helped pave the way for the American torture regime.
So, of course: John Yoo is a featured speaker at Tea Party events.
Now: There are undoubtedly many fine and sincere Tea Party participants who legitimately want to see government restrained and fitted for a Constitutional straightjacket. That's fine. But even now, it's easy for me to believe that there's also a sizable chunk of people who didn't mind expanding deficits and tyrannical government overreach as long as a Republican is president. Tea Partiers who turn out for a John Yoo speech? Almost certainly in the latter group.
