into Joe's motivation and have found clues here:

Back in the Vietnam era, he seemed the essence of a historic political migration: white males fleeing the feminized, antiwar, politically correct Democratic Party
The percentage of white males identifying themselves as Democrats has declined from 47% in 1952 to about 25% in 2004. Much of that decline was an unavoidable consequence of two honorable positions the party took in the 1960s: in favor of civil rights and against the war in Vietnam. But civil rights slid into special preferences (for everyone, it seemed, but white men), and Vietnam slouched, all too often, into reflexive pacifism and a distrust of the military.
Joe clearly has issues that are quite a bit older and deeper seated than any dust-up over a FISA bill. I don't doubt that his own fears about being considered "feminized, antiwar, politically correct" drive a lot of what can only be considered irrational behavior.
