Another round of polling released today.
Michigan: Romney vs. Obama Baydoun/Foster (D) Obama 44, Romney 48 Romney +4
Wisconsin: Romney vs. Obama PPP (D) Obama 47, Romney 48 Romney +1
Both were taken by Democrat pollsters. Interestingly PPP tends to have a 5-8 point skew towards Obama and still shows Romney with a lead in WI. In Michigan that poll was of 1700+ likely voters. Romney with a 4 point margin there.
This was the first recent Michigan poll showing Romney leading so take the results with a grain of salt but signs of trouble for Obama can't be denied.
