Thomas Schaller argues this point in today’s New York Times.  He notes,

“Virginia, however, is the one Southern state that Mr. Obama has a reasonable chance of winning. And it’s precisely because the home of Robert E. Lee, as NBC News’s political director, Chuck Todd, has suggested, is seceding from the Confederacy.

“The demographic makeup of the electorate in Virginia is unlike that of any other state in the South. The black population in Virginia is, as a percentage, among the lowest in the region. And during the last two decades, the state has also experienced a huge influx of upscale non-Southerners, who have taken over the Washington suburbs of northern Virginia. (Florida is a perennial target for similar reasons. With a relatively small black population, a big Hispanic voting bloc and a large contingent of relocated retirees from the North, it is the least Southern of the Southern states.)

“In the rest of the South, Mr. Obama cannot overcome reality. Even if unprecedented numbers of black voters turn out to vote for him, the white vote will serve as a formidable counterbalance. Mr. Obama should not hope to capture states in the country’s most racially polarized region.”

On MSNBC, they’re focusing on whether Bill Clinton can help in the South.  The panel suggests its a mixed bag, but Clinton did win several states below the Mason Dixon line the last time he was on the ballot.  Of course, he’s not on the ballot in 2008.
