As for the cowardly Kerry going through his green and libertarian party friends, he's just trying to satisfy his loony-left base. He thinks that if he joins in the drumbeat of this being a "stolen" election, the democrats will give him another chance to go for the job in '08 that was wrongfully denied him in '04--a Richard Nixon sort of scenario.
This is just a futile exercise, it's not going anywhere. Even if they were to find a way-out-there leftist judge willing to throw out the results, the OH supreme court would reverse it. They also can't fish for more votes since the 2R-2D county election boards would have to get a republican over to their side for any vote to count for Kerry. And unless they have "proof" that meets the legal bar and is prosecutable, it doesn't rise above the level of sore-loser, partisan accusations.
Him closing the gap by that much isn't a big surprise either. Dems seem to gain after election night results, but rarely by a huge amount.
