Democratic U.S. Senate nominee Betty Castor's first commercial in South Florida aims to turn what rival Republican Mel Martínez sees as a strength into a weakness: his ties to President Bush.
Martínez, Bush's former housing secretary, frequently trumpets their relationship to boost his credibility and popularity. But Castor apparently thinks that such a close alliance with the candidate who just barely won the state four years ago is a vulnerability, at least in South Florida.
