Polls aren’t always reliable but research does show that they get more accurate the closer it is to election time. With just a couple of weeks before America votes in the midterm elections, let’s take a look at how the tightest races around the country are shaping up.

In New Hampshire, Democratic incumbent Jeanne Shaheen leads Republican challenger Scott Brown by 3 percent, according to a new Suffolk/Boston Herald poll. Shaheen has now led or tied Brown in all but one poll out of the Granite State. A recent New England College poll had Brown up by 1 but that’s the only poll to suggest Brown ahead. Shaheen appears to own a slim lead and is likely to hold on to her seat.

In North Carolina, a new PPP poll shows Democratic incumbent Kay Hagan leading Republican challenger Thom Tillis by 3 percent while a new Rasmussen poll has her up by 2. A recent SurveyUSA poll had Tillis up by 1 but that one surveyed very few people and has a significantly higher margin of error. That poll aside, Hagan has now led Tillis in every poll going back to September.

In Georgia, Republican David Perdue looked like he was going to coast to an easy win. Instead, his business past and outsourcing practices have soured voters on the former Dollar General exec and Democrat Michelle Nunn now owns a slight lead.

After poll numbers through early October showed Perdue’s lead slipping, a WSB-TV poll had the race tied by October 9 and a new Survey USA poll and WRBL/Ledger-Inquirer poll have Nunn up by 1-3 percent.
