Not in the South, anyway. As you probably know, Democrat Travis Childers won a special election on Tuesday in a conservative Mississippi congressional district, scoring a big upset for the Dems that many political observers say is a sign of Democratic victories to come. The Republicans botched one part of the strategy, apparently (from the Times, via the Stump):
But the Republican strategy of trying to link Mr. Childers to more liberal national Democratic figures fell short, as it did in Louisiana. Indeed, voters here were bombarded by advertisements equating Mr. Childers with Senator Barack Obama, a tactic intended to turn conservative whites away from Mr. Childers.... [It] may have helped Mr. Childers more than it hurt him, as campaign aides reported heavy black turnout, heavier than in a vote three weeks ago when he came within 400 votes of winning.
