As part of his increasingly active campaign schedule, former Florida Gov. Jeb Bush (R) cut a web ad for one of the Republicans vying to challenge Rep. Alan Grayson (D-Fla.).

Bush appeared in the 30-second spot for former state senator Dan Webster (R), after endorsing him last month. 

The country faces challenges, Bush says in the ad. "I can think of no one better prepared to meet those challenges than Dan Webster."

Webster is one of seven Republicans competing in the Aug. 24 primary to face Grayson. Bush said in July he has no plans to run for president in 2012. But he has become increasingly active campaigning for candidates around the country.
