The Republicans are in danger of being pushed into a Southern redoubt. Their increasingly narrow regional and demographic base bears a remarkable resemblance to the old areas of Democratic strength during the Republican heyday after the Civil War.
The GOP controls both Senate seats in 17 states. Nine of these are in the South or border South, and four are in the inner West. (Three of those four states, Idaho, Wyoming and Utah, are about as solidly Republican as any in the country.) There are two states far outside the Republican comfort zone where the party holds both seats, Maine and New Hampshire. And in both of those, an incumbent faces a serious challenge from the Democrats next year.
But trends within the states are as important as national geography. Outside the Deep South, Democrats are on the verge of becoming the dominant party in the suburbs and are pushing into the exurbs. In Virginia, that offensive was central to the Democratic victories of Gov. Tim Kaine in 2005 and Sen. Jim Webb in 2006. But the implications go beyond a single state.
Yet at the very moment when Republicans need unity against Warner, Davis could face an ideological showdown with former governor Jim Gilmore or, possibly, former senator George Allen, who lost narrowly to Webb last year. Both Gilmore and Allen are down-the-line social conservatives. This would give them an advantage in an internal party fight but would limit their general election appeal in the suburbs.
The outcome will determine whether Virginia Republicans define themselves as conservatives oriented toward the Deep South or as middle-state moderate conservatives comfortable with the rise of suburban politics.
