I doubt McCaskill is only down 2... Obama probably loses this by 7-9 points.
M-D is one of the best pollsters out there and I could easily see Adkin willing this.
They seem to lean Republican in some states in 2008, but got others well. They nailed Florida and Missouri, but had McCain up in Ohio and North Carolina. They were perfect in 2004. I really want to see their Ohio poll this year. They nailed it in 2004. If Obama is winning in the final Mason-Dixon Ohio poll, that will give me the clue that Obama has won.
The one time they leaned Dem was in 2010 when they had Alex Sink ahead by three in their final poll in the Florida governor's race.
