Reid will win, the media will call it a huge defeat for the tea party and Republicans, and a newly-emboldened Reid will push an unprecedented lame duck agenda, including card check, amnesty, dream act, judges and more.
Actually, 'we' win either way this goes.
If Reid wins and the Senate stays in RAT control (by a hair), then this sets us up nicely for a stupendous contrast for 2012. If REID remains - he will continue to be the 'poster boy' for everything bad about RAT control of the Senate, something nicely to remind Americans thru 2012.
