If he can get as much of the vote percentage that he got in Maryland (29 %), I'll give you five bucks.
I would be satisfied if you just took the time you use to smash Keyes' "electability" or other qualities on this forum to instead praise his good qualities, or even the qualities of another candidate who you find more "electable." I'd say I would give you five bucks, but if I had that to spare, I'd send it to the Keyes campaign.
You may also choose to smash Obama's record every chance you get. Time better spent, IMO, than showing distress or disappointment in his opponent.
