“Historically, the major parties in America have yoked together the most disparate groups for long periods. The New Deal Democrats were a party of Northern liberals and Southern segregationists. But once Lyndon Johnson committed the Democrats to civil rights for African Americans, the white South up and left — a process that took 40 years to complete but that left the Democrats struggling to assemble congressional and presidential majorities and that converted the Republicans into a party where Southern values were dominant. Now the non-Southern bastions of Republicanism may themselves up and leave the GOP, seeing it as no longer theirs.” The American Prospect‘s Harold Meyerson sees potential for a realignment of northern moderates come Tuesday. Well, let’s hope. Chafee looks like toast (and he’s acting like it, too), but there are still a lot of undecideds — between 15 and 20% — in that Rhode Island race. And, lest we forget, our very own president, much as he’d like us to think otherwise, is a scion of the North as well.
