Larry J. Sabato's Crystal Ball takes a look at the Dems' House prospects, both specific and general, and provides snapshots of key races. Sabato presents some interesting "leaning" and "likely" House race charts and ventures what we hope is a conservative prediction:

every initial indication suggests that 2008 will be a consolidation election for the Democrats. They may add a few seats, or lose a few, but their majority is unlikely to be threatened...it appears more likely that Democrats will gain seats in the House, thus padding their new majority. How many seats are added, or indeed whether this tentative prediction holds up at all, will depend partly on the identity of the presidential candidates and the coattails they generate..

The Cook Political Report's House of Reps guru David Wasserman sees Democrats picking up between two and seven House seats in '08. MyDD's Jonathan Singer guestimates a 10-15 seat pick up. He reasons:

the National Republican Congressional Committee remains mired in debt less than a year out from election day while the Democratic Congressional Campaign Committee is as flush with cash as it has ever been with a net $29 million in the bank. This magnitude of this feat cannot be overstated...Not only are the Democrats enjoying a real advantage in the money race, the Democrats have also seen a lot more success in recruitment than the Republicans.

Dividing the difference between Singer and Wasserman gives Dems a 8-9 seat pick-up, which is still way short of a working majority without a Dem President. Even more disturbing, if this pick-up percentage applies to the Senate, the Dems' one-seat Senate majority seems even more fragile, especially with Lieberman cosying up to Republicans. Maybe it's too much to expect another wave election, but a presidential landslide with coattails ought to be doable in a war-weary nation.
