State Sen. David Brinkley, who is running for the Republican nomination in Maryland's 6th Congressional District, is airing the first television ad of his campaign Friday.

The 30-second spot takes aim at incumbent Rep. Roscoe G. Bartlett without mentioning him by name. "Our fiscal crisis was caused by incumbents -- our incumbent, too. Enough is enough."

Brinkley, of New Market, is running against seven other Republicans, including Bartlett, in the April 3 primary. The campaign said the ad will continue through the election.
