Wonkette says this campaign ad for GOP front-runner Sen. John McCain will start playing locally now that the “Potomac Primary” on Feb. 12, made up of Maryland, D.C. and Virginia, is one of the next big strategic primary dates on the calendar.

Below is the one of the two ads Sen. Barack Obama is now running in Maryland.

UPDATE: This video is running in Maryland, according to Obama’s campaign web site linked previously. But the end of the video has the wrong election date for Maryland (it asks Maryland voters to vote on Feb. 5) — so we can imagine (or at least hope) that this is not the exact spot that’s running in the state right now. Eep! This video, which is also running in Maryland, has the correct date listed at the end.
