When the Democratic National Committee chose Charlotte as the site for its national convention, it seemed like a good idea at the time. It’s a beautiful state with good weather in September. Obama had carried the state in 2008. The local Dems seemed to have it together. Well, Democrats are learning that a lot can change in a few short months:

Simply put: North Carolina looks like a mess for Democrats.

The state’s Democratic governor, Beverly Perdue, is so unpopular — her job approval has been fluctuating from 30 percent to 40 percent for months — that she wisely decided not to seek re-election this year. A recent survey by Public Policy Polling, a Raleigh-based Democratic polling firm, showed only 60 percent of Democrats approve of the job the governor is doing. …

But it gets worse.

According to the Bureau of Labor Statistics, North Carolina’s preliminary unemployment rate for March stood at 9.7 percent, lower than only three states (California, Rhode Island and Nevada) and the District of Columbia. Apparently, the Obama administration’s jobs recovery has not shifted into high gear in the Tar Heel State.

Of course, if the state’s economy is a mess, it’s still in better shape than the North Carolina Democratic Party.

Two weeks ago, the state party’s executive director, Jay Parmley, resigned amid accusations of sexual harassment. North Carolina Democratic Party Chairman David Parker, who accepted Parmley’s resignation but seemed to defend him, has also come under fire. Some Democratic activists are now demanding his resignation.

Finally, the president will accept his party’s nomination — and presumably beat up on corporate America and the wealthy — at Bank of America Stadium (after a couple of days at Time Warner Cable Arena). Expect the press to point out the irony, which could put President Barack Obama’s campaign on the defensive more than a few times.
