U.S. Senate Republican Leader Sen. Mitch McConnell (R-KY) and his wife Elaine Chao wave to a crowd of campaign supporters after defeating Tea Party challenger Matt Bevin in the state Republican primary elections in Louisville, Kentucky, May 20, 2014. McConnell easily dispatched a Tea Party challenger in Kentucky on Tuesday to win nomination to a sixth term, setting up one of November's most expensive and hard-fought Senate races against Democrat Alison Lundergan Grimes. McConnell's decisive victory over conservative businessman Matt Bevin was one of the highlights of the busiest election night of the year so far, as voters in six states picked candidates for November elections that will decide control of Congress.
