Believe it: The Democrats could lose ... 100 seats

That said, I think those who suggest that the House is barely in play, or that we are a long way from a 1994-style scenario are missing the mark. A 1994-style scenario is probably the most likely outcome at this point. Moreover, it is well within the realm of possibility – not merely a far-fetched scenario – that Democratic losses could climb into the 80 or 90-seat range. The Democrats are sailing into a perfect storm of factors influencing a midterm election, and if the situation declines for them in the ensuing months, I wouldn’t be shocked to see Democratic losses eclipse 100 seats…

The President’s weakness in these states reveals another problem for his party. Since he is weak in Republican areas and swing areas, and yet doesn’t have horrible approval ratings overall, he must be very, very popular among his party’s base. Some polls have his approval ratings among African Americans at 95%. Even in Massachusetts, Martha Coakley managed to win the First, Seventh and Eighth Districts, which are home to the state’s liberals and minorities.

The problem for the Democrats is that these voters are packed into a relatively few states and Congressional districts nationwide, diluting their vote share. This is why the median Congressional district is an R+2 district. Thus, the President could have a relatively healthy overall approval rating, but still be fairly unpopular in swing states and districts. The increased enthusiasm that Obama generated among minorities, the young and the liberal is useful, but only if it is realized in conjunction with Democratic approval in a few other categories.
