1. Eric Cantor
The Virginia lawmaker, currently the House minority whip, could very well become majority leader in a GOP-controlled House of Representatives if current minority leader John Boehner (R-Ohio) is elected speaker of the House. Cantor, who is particularly active on foreign-policy issues involving Iran and Israel, could see his role expand significantly if he is given the power to set the House floor agenda and therefore determine which bills are considered, in what form, and when.
That could spell trouble for the administration's foreign operations budget, which funds the State Department and sets levels for U.S. non-military assistance around the world. Republicans are threatening to withhold aid to countries they see as not being wholly supportive of the United States and Cantor told the Jewish Telegraphic Agency that the president's proposed budget might have to be rejected outright if Republicans take power -- after separating out U.S. aid for Israel, of course.
