New York Gubernatorial Republican winner Carl Paladino had 16,117 fans over his opponent Rick Lazio's 13,499 fans and in the Republican Wisconsin House race (7th district), Sean Duffy dominated Dan Mielke with 6,360 fans to 172 fans respectively.
Kelly Ayotte had 3,506 fans in the Republican New Hampshire Senate primary over her opponent Ovide Lamontagne with 2,126 fans.
While in New York, Congressman Charlie Rangel had only 273 fans, he posted more frequently than his opponents, who also had a small Facebook following.
"Overall, we've seen that candidates are using Facebook as a free resource to reach voters directly, without having to go through the traditional media filter or pay for television and radio ads," Facebook spokesperson Andrew Noyes said in an e-mail to CNN. "Campaigns are using Facebook to organize and communicate with voters in a way unimaginable a decade ago. The media now uses Facebook to identify trends, track candidates, and reach voters. And voters increasingly expect to be able to interact with and examine candidates on Facebook and tell their friends who they are supporting."
