Buchanan, Castor among U.S. House incumbents to survive Tuesday.

An anti-incumbency fervor that many say is sweeping the country this election year did not extend to Florida and the seven incumbent U.S. House members who faced intra-party challenges in today's primary.

As of late tonight, five of the incumbents -- including U.S. Rep. Vern Buchanan, R-Sarasota, and U.S. Rep. Kathy Castor, D-Tampa -- had won their respective primaries.

Buchanan and Castor cruised to easy re-nomination wins, with Buchanan receiving 83.5 percent of the vote in his GOP primary race against Don Baldauf; and Castor receiving 85.4 percent in her battle with Democratic challenger Tim Curtis.

They also start out their re-election campaigns with large fund-raising and name-recognition advantages over their respective challengers.
