Forty years ago today, President Nixon addressed the nation to announce he would be resigning the next day -- the only time in US history this has happened. Today, President Obama announced the US will be dropping bombs on Iraq once again. That's a pretty heavy-duty amount of the past to contemplate, in one week.
The message this sends to other Republicans in Congress (both House and Senate) is that this can happen to anyone. The fear this is going to create may become all-encompassing in the House, and possibly even the Senate (if Republicans win control of the chamber this November). The Tea Party sword hanging over their heads is now plain to see.
