If we lose the House, Obama may be better positioned for 2012. If we lose both the House and the Senate, we're in for a lot of trouble. Vicious stuff all aimed at slowing any follow-through change for our President, who's been delivering it too fast for the right and too slow for the left.
It's not worth the risk. Get out and vote for any Democratic fed that you can. Otherwise don't whine after when your health care reform gets strangled.
