Marc on what a Democratic blowout would do to the GOP:

To the extent that geography correlates with ideology among congressional Republicans, a major sweep by the Democrats could really be in a position to completely break the gluons that bind the broader party together. The GOP will lose a disportionate number of seats in the Northeast, Midwest and West and keep a disprortionate number of seats in the South. So the remnant of the party, as it were, will be right-wing Southern conservatives.... even more so that it is now.

This is what happened to the British Tories after the Blair landslide in 1997. The rump was even more toxic after the defeat than before it. A decade later, and they still aren't back in power, but they have managed the very difficult task of getting back to the center. It isn't easy.
