Obviously an exercise, inspired by the flood of 8-0 Democratic Marylands. Originally I had attempted to make five Republican seats in Maryland, but while it was possible to make five seats won by McCain it would have been a huge overreach and Republicans would have been unlikely to hold all five seats in even a neutral year (possibly none in a Democratic wave). Given that, the exercise became a matter of shoring up four seats as much as possible. While Maryland is quite a blue state these years the Democratic voting base is heavily concentrated so forcing it into four ultra Democratic seats was entirely possible. The remaining four Republican seats all ended up with a 44-54 Obama/McCain lean.
