-Terry Branstad has the best approval numbers this month that we've found for him since he took office. 49% of voters approve of the job he's doing to 37% who disapprove. He leads a generic Democratic opponent in a head to head match up by an identical 49-37 spread. Who knows what the political climate will look like in 2014, but at least for now he'd be in good shape if he was up for reelection.
-Tom Harkin got a pretty easy ride to reelection in 2008 but if he runs for another term in 2014 it has the potential to be a strong Republican pick up opportunity. Harkin's approval numbers aren't terrible- 44% of voters approve of him to 38% who disapprove. But against a generic Republican foe he leads only 45-43. Given those numbers the GOP ought to be able to recruit a pretty strong candidate next time.

That's actually up a net 6 points from July though, mostly because he's gone from 50/15 to 57/8 with Republican voters over the last month. Perhaps they liked his controversial comments last week.
