It is official: Evan Bayh has announced that he will not seek reelection. This may or may not be a wise move. After all, the mood of the country could easily swing in the opposite direction just as quickly as it has, as of recent, swung from left to right. The Republicans aren't particularly trusted right now, and it is telling that they are running not as "Republicans" but rather as "outsiders".
The more interesting question that the Evan Bayh retirement raises is this: President Obama more or less hung Democrats in moderate districts out to dry with his health care and cap-and-trade legislation. Is it possible that Bayh will return the favor and mount a primary challenge against Obama in 2011? It all depends on the mood of the country, but if it continues to shift rightward, I would rule it out.
