A guy wearing a John Kerry button walks into a bar just as the late news is showing a man standing on the edge of a building. The Kerry guy bets that bartender $50 that the man on TV won't jump. A moment later the guy does jump, so the bet is settled. But the bartender says "Aw, I can't take your money - I saw that clip on the early news". The Kerry guy says "yeah, so did I - I sure didn't think he'd jump again".
Was that a gratuitous Kerry reference? Of course. But then his noncynical followers (assuming he has any) are being asked to believe that he supports the troops when he didn't even support the guys he nominally fought alongside. They're asked to believe that he's not going to raise their taxes despite the long Senate record he's unusually quiet about. They seem willing to believe that Kerry can simultaneously insult our allies while attracting more of them to the wrong war in the wrong place at the wrong time. And they think that by electing a Veep that has a history of raising medical costs and driving obstetricians out of business they can offer better and cheaper medical care.
They're sure going to be surprised if they get what they vote for and Kerry turns out to be the same SOB he's been for the last 35 years.
