The Democratic National Committee is running a radio ad urging Norm Coleman to exit the Senate race and allow Democrat Al Franken to be certified.

Now, Coleman doesn’t seem like the type to give up on a legal fight just because he hears a radio ad. But there’s not much chance he’s going to hear it, anyway.

Total cost of the ad buy? $850.00. No, there are no missing zeroes. It will air twice a day for two days on one station, and an unknown number of times on the Air America affiliate.

But I guess it’s money well spent when it spurs articles and coverage in the Minnesota Star Tribune, CNN, Politico, the Washington Post, the Minneapolis City Paper, Talking Points Memo, and Minnesota Public Radio.
