Why do you have Massachusetts at Lean R?
Being cautious, which seems appropriate, though if Obama continues to have trouble where the polls say, Massachusetts will continue to be less D at the Presidential level (not competitive, but you know what I mean), thereby helping Brown immensely.
I wouldn't be surprised if Obama's numbers were in the negatives at this point in MA but Scott Brown's glow could be fading by this point, especially after the debt ceiling debacle which seems to have damaged every Congressional incumbent in the nation.
I want more polling! Too many Democrats are resigned to losing this race.
