No, Kerry was not portrayed as particularly smart (not that you could tell, really, given Meyers' ****** impression.) He tried to get out of the phone call by saying he was going into a tunnel and the call was breaking up, but rather than making crackling noises he just said the word 'crackle' over and over.
Of course the answer to "how would that impact the election?" is the same answer you were given when you whined about Fey's Palin impression. SNL does not have even a minor impact on elections, and never has. An SNL sketch is a trailing indicator, not a leading one. You won't accept this, of course, because it doesn't fit your world view. If SNL skits don't really matter, you think it undermines your claims of liberal persecution.
Rational people change their theories based on new facts. You try to change facts to fit your theories. It's maybe the principle reason why you lose pretty much every political argument you ever have on these boards, but conveniently it's also the principle reason why you don't think you lose them so it really works out for everybody. You remain the board's *****, so we get the entertainment value of your idiocy, and you never wise up to the fact that you are the board's ***** so you don't leave.
