Michele Bachmann isn't running again.
I didn't see anywhere her reasoning for the decision, only that it is *not* because there was a scandal in her presidential campaign involving improper payment of and Iowa staff person. My hunch (completely unsubstantiated) is that she wants to run for governor. We just got through a tough legislative session where the democrats pissed a lot of people off so she'll probably think she can build on that. But the people in the whole state of MN are not as stupid as the people in the district who voted her in for 5 sessions. Plus, she only narrowly won last time.
