2014 Senate Polls Update: Iowa, Alaska, Arkansas, Kansas, Michigan

There was a handful of polls tracking the closest 2014 Senate races released this week and presented good and bad news for both parties as Election Day nears.

Iowa is by far the closest race of any this election cycle as two new polls show a dead heat between Republican Joni Ernst and Democrat Bruce Braley. Since July, four of five polls had the race as an even tie while a CBS News/New York Times poll released in early July had Ernst leading by one point.

Arkansas is another state that could really go either way. After Republican challenger Tom Cotton led two July polls by 2 percent, incumbent Democratic Senator Mark Pryor leads Cotton by one point in the latest Rasmussen poll so this race is a virtual tie as well.

In Alaska, where incumbent Democratic Senator Mark Begich led by 4 percent in the last PPP poll in July, a new Rasmussen survey shows Republican challenger Dan Sullivan leading Begich by 2 percent.

In Michigan, Democrat Gary Peters appears to be the frontrunner over Republican Terri Lynn Land, the only question is by how much. While a Rasmussen poll and EPIC-MRA poll show Peters up by 6 percent, a Harper poll only has Peters leading by 1 percent and a Mitchell Research poll has Peters up by 2.

In Kansas we see an interesting race as it is one of the few three-way races in the country. Republican incumbent Pat Roberts currently leads Democrat Chad Taylor and independent challenger Greg Orman but Orman is gaining ground.

The latest Survey USA poll has Roberts with 37 percent, Taylor with 32 percent, and Orman with 20 percent.
