"What's Making Karl Rove So Optimistic about the Election?"

Steven D on Booman Tribune (text with video of Clint Curtis testifying on Diebold vote hacking):

One, assuming Republicans do lose control of either house of Congress, Rove's pre-election public statements (and those of President Bush) have laid the groundwork for Republican post-election lawsuits, recount demands, allegations of Democratic election fraud and other assorted post election chaos. The goal would be to mount a last ditch defense of Republican control of Congress, and to make that defense credible they have to nourish the meme in the minds of the media and the American Public that the polls now show Republicans should win the election. The objective would be to prevent seating enough Democrats to keep control of the House or Senate in GOP hands after the dust cleared, or to cast doubt on the legitimacy of any Democratic victory, and thus seek to limit the power and authority of any Democrats in a position to investigate the White House.

Second possibility? C'mon, what do you think it will be? I'll give you three guesses and the first two don't count.
