It may be too good to be true, but that's the impression I got from two state polls released. In Massachusetts, Obama is down to 58-42% approval compared to an election day win of 62%-36% (Rassmussen). In Colorado, Obama has a net approval of 49%-45% compared to 54%-45% on election day (PPP). Rasmussen's tracking poll also tightened slightly to 54%-45%.
On the other hand Gallup shows Obama's approval largey unchanged at 63%, so it could be a statistical blip.
