Rasmussen shows Bush with job approval of ~52% in MN, PA, and MI. Perhaps he will win them also.
The following site has a list of Bush JA's for battleground states: http://www.iomada.com/bummy/index.asp Here's some results: FL 54, IA 53, MN 51, NH 47, NM 49, OH 52, PA 52, WI 53. If 50 is the magic number, this would have Bush holding all his 2000 states except NH and adding IA, WI, and PA.
