Another poll diary, some good news for Obama. I suppose none of these are "swing states," but I guess there was still an outside shot McCain might be competing in Iowa. Basically, SUSA - a strong pollster, top-rated by Nate at 538 - has Obama blow outs in Iowa and Wisconsin. And in South Carolina, Obama is behind by a respectable margin:
Iowa: Obama 55, McCain 40
Wisconsin: Obama 55, McCain 39
South Carolina: McCain 52, Obama 44
Added bonus - Obama is blowing McCain out in early voting in Iowa.
