The national GOP supported Chafee in the primary campaign, believing that he was the most likely candidate to hold the seat in the general election. Senator Mitch McConnell of Kentucky, John McCain of Arizona and Laura Bush appeared at fundraisers for Chafee, while Senator Bill Frist's PAC donated to Chafee. The National Republican Senatorial Committee also ran ads in the state supporting Chafee. Steve Laffey, however, picked up many endorsements from Republican town committees throughout Rhode Island, the national group Club for Growth, and former candidate for the party's Presidential nomination Steve Forbes. On July 10, 2006, the National Republican Senatorial Committee filed a complaint with the Federal Election Commission against Laffey, saying that he had included a political communication in tax bills mailed to residents of Cranston.
