The ad from Crossroads GPS, a shadowy conservative political group formed by Karl Rove, starts today on Florida TV airwaves and will run for two weeks. Total spending on the Florida effort is more than $531,035.
The spot is part of the group's $20 million ad campaign timed to national debt negotiations in Congress. Similar ads are targeting senators in four other states.
