More Bad News For Democrats as Senate Races Swing Republican

Last week we looked at how President Obama’s sagging approval and favorability ratings are dragging down Democrats in gubernatorial races. The same phenomenon has been the case in the Senate races as a slew of new polls shows Republicans taking the lead in their respective elections.

In Arkansas, where incumbent Democratic Senator Mark Pryor had led by as much as 10 points in the spring, a new CBS News/New York Times poll shows Republican challenger Tom Cotton leading by 4 points. A Rasmussen poll, a Magellan Strategies poll, and an Impact Management Group poll all have Cotton leading by 4 percent as well.

In Kentucky, where recent Survey USA and Magellan Strategies polls had Democratic challenger Alison Lundergan Grimes leading by 1-3 points, incumbent Senator and Minority Leader Mitch McConnell leads by 4 percent in the latest CBS/NYT poll and by 2 percent in the latest Survey USA/Courier-Journal poll.

In North Carolina, where incumbent Democratic Senator Kay Hagan led all through June and early July, the new CBS/NYT poll has Republican challenger Thom Tillis pulling ahead by a slim one-point margin.

In Louisiana, where a recent PPP poll had the race tied and a Rasmussen poll had incumbent Democratic Senator Mary Landrieu leading by 3, the new CBS/NYT poll has Republican challenger Bill Cassidy taking a 1 percent lead.

In Iowa, where Democrat Bruce Braley had led just about every single poll to come out of the Hawkeye State, the new CBS/NYT poll has Republican Joni Ernst leading by 1 percent while a new NBC News/Marist poll has the race tied.

In Michigan, where Democrat Gary Peters had led every single poll since April, the new CBS/NYT poll has Republican Terri Lynn Land ahead by 1 percent.

In Georgia, where a recent Landmark Communications poll had Democrat Michelle Nunn up by 4 percent, the new CBS News/NYT poll has Republican David Perdue leading by 6 percent.

There is still time but with most primaries over, the Republicans find themselves in very good position heading toward the November midterms.
