Which One of These Is Not Like The Other?

Jeremy Lott, with whom BT has previously tangled (see comments), is a bit of a zealot about getting rid of the Vice Presidency.

Like most zealots, he doesn't mind going overboard to make an otherwise reasonable point:

The vice presidency has also put troubling and divisive men only a heartbeat away. Aaron Burr, Henry Wallace, Al Gore and Dick Cheney came too close for comfort.

The first sentence is indisputably true. But re: the second: show your work, Mr. Lott. Or did Al Gore shoot a man in the face while the nation slept?
