According to new NBC/Marist polls, the GOP is leading in Arkansas and Kentucky, which could mean they'll soon control the Senate. If the Republicans take the Senate in November, they'll control both houses of Congress.
The Arkansas race consisted of Republican Rep. Tom Cotton and Democratic Sen. Mark Pryor. When asked who they would vote for if Arkansas citizens were going to vote today, Cotton received five more points (45-40) than Pryor. In the Kentucky race between Republican Senate Minority Leader Mitch McConnell and Democratic candidate Alison Lundergan Grimes, McConnell leads by eight points (47-39). The same poll shows Colorado's Democratic incumbent Sen. Mark Udall maintaining his position by a slim margin.
