With a loss by Sen. Mark Pryor, the first Democratic incumbent fell in the 2014 midterms, setting off a chain of events that brought the Republicans a new Senate majority. The man who would lead them in Congress, Sen. Mitch McConnell, coasted to a win in Kentucky.
McConnell was projected to defeat Democrat Alison Lundergan Grimes by a 15-point margin, 56 percent to 41 percent, with almost a third of the vote tallied.
In Arkansas, Democratic Sen. Mark Pryor lost to Republican Rep. Tom Cotton, a first-term member of Congress. Pryor has served in the Senate since 2003.
