CNN Polls: Missouri, Nevada Senators face close races in re-election bids

The sitting Senators in two of the most closely watched re-election fights this fall are running nearly even with their challengers, according to new CNN polls conducted by SSRS.

Democratic Sen. Claire McCaskill edges challenger Josh Hawley 47% to 44% among likely voters in Republican-friendly Missouri, while Republican Sen. Dean Heller stands four points behind his Democratic challenger Jacky Rosen in Nevada (47% Rosen to 43% for Heller), which has broken for Democrats in each of the last three presidential contests and has been a regular Senate battleground in the last decade. CONT.
