Senate races in two key states are growing tighter in the final week of the midterm election, according to new polls.

Fox News polls released Wednesday showed margins have narrowed in North Dakota and Arizona, two states that will help determine which party controls the Senate next year.

It’s a narrower margin than a Fox News Poll released on Oct. 3, which had Cramer leading Heitkamp by 12 percentage points at 53 percent to 41 percent among likely voters.

The poll was conducted from Oct. 27-30 with live telephone interviews of 789 likely voters and includes a margin of error of 3 percentage points.
