"Mary!" Pat Buchanan calls Bush: "A TYPHOID MARY!"

Pat Buchanan tonight, on msnbc's "Countdown," discussing Republicans' reluctance to be seen campaigning with the FAILED Bush White House, said
President Bush, is:
"...A TYPHOID MARY!"
Now that's funny!

Wikipedia clarifies for us the contemporary-use of the "toxic" term:

Today, a "Typhoid Mary" is a term for a carrier of a dangerous disease who is a danger to the public because they refuse to take appropriate precautions or cooperate with the authorities to minimize the risk.

"Danger to the public," CHECK!
"Refuses to cooperate," CHECK!
Buchanan, seems ABOUT RIGHT(!), Herb.
