cinyc,
I misread your chart. The second to last column looked like swing/trend since the difference between the two was similar to the projected swings discussed yesterday as a parameter for a Brown victory. MA-8 having the lowest swing and MA-3 having the highest makes more sense.
Well, it is probably unlikely that Republicans will win a single house seat this year in MA, unless a vacancy happens to occur, I would agree. But, consider this. If a Democrat won a special Senate election in Louisiana 52-47 and carried 4 of 7 districts, I would guess that Democrats might get a tad excited about their prospects for the fall elections.
Perhaps, but keep in mind that Louisiana has a history of electing Democratic Senators--in fact every election the past 100 years except Vitter in 2004.
True enough. But in today's Louisiana, I think that Democrats would be hopeful were this to happen. Also, in any of her wins, I have to wonder if Landrieu topped 50% in any CD but the New Orleans 2nd.
