This $25 million communications company works with Republican candidates and conservative advocacy groups. The business did extensive work on the 2004 Bush re-election campaign. CEO Jeff Larson is currently moonlighting as CEO of the convention host committee. In that capacity, he oversees a $58 million budget, 250 employees, and more than 8,000 volunteers. Larson says he's excited to see old friends (and meet new ones who need tickets for the convention), but he would have been equally happy, he says, to host the Democratic convention.
