With elections just over a month away, we have a ton of polling to look at to get a good idea of what is happening in some of the tightest races in the country. Let’s take a look at the latest numbers to see how things are shaping up as Election Day nears.

In Iowa, where Republican Joni Ernst has been neck and neck with Democrat Bruce Braley, Ernst has taken a 6 percent lead according to a new Des Moines Register poll. That’s the second poll this month, the last one being a Quinnipiac poll released in mid-September, to show Ernst up by six.

In North Carolina, Democratic incumbent Kay Hagan has maintained a 2-5 percent lead but has been unable to pull away from Republican challenger Thom Tillis. Hagan has led every poll released in September and they all have her a few points ahead of the challenger with about a month of campaigning left.

In Arkansas, Republican Tom Cotton has led all but two polls since May and leads the latest Rasmussen poll by 7 percent over Democratic incumbent Mark Pryor. Though Pryor has shown signs of life and Cotton has not opened up a huge lead in any of the polling we’ve seen, Cotton looks to be the odds-on frontrunner to win Arkansas for the GOP.

Louisiana is interesting. Rather than a general election, the state will hold an open senate primary on Election Day before the top two vote-getters face off in a runoff in December. While Democratic incumbent leads Republican Bill Cassidy and fellow GOPer Rob Maness in the open primary polls, she trails Cassidy by 3 points in the latest general election poll. It looks like Louisiana is likely to go back in the red come December.
