So with it now all but confirmed that SC Republican Rep. Joe Wilson was the one who called out “Lie!”:http://www.politico.com/blogs/bensmith/0909/A_voice_from_the_floor_on_illegal_immigrants_Lie.html during President Obama’s speech tonight, a couple questions for all you presidency scholars out there. Is this sort of thing unique in recent years? When was the last time someone essentially yelled at the president during an address to Congress? How about historically – did this sort of thing go on more often earlier in our nation’s history?
