Back in April I wrote a blog post about how a lot of class of 2012 Democratic Senators were posting pretty bad approval ratings.
We've seen a lot of change in those numbers for three of those folks in the last month.
Sherrod Brown's approval has improved a net 11 points since March from -7 (32/39) to +4 (38/34).
Bill Nelson's has improved 9 points over a similar time period from -3 (37/40) to +6 (39/33).
And Bob Casey's since April has improved 8 points from -7 (31/38) to +1 (36/35).
None of those numbers are great and all three of these guys will probably be on Republican target lists in 2012. But the improvement is undeniable and I think reflective of Democrats generally being in better shape than they were at the height of the health care debate.
