A new poll in the Iowa Senate race shows Republican Joni Ernst with a more than six-point lead over Democrat Bruce Braley.
Ernst earned 48 percent of the vote in the Loras College poll of likely voters released Friday well above Braley's 41.7 percent. More than 10 percent said they are undecided. It follows a Rasmussen Reports poll, also released Friday, that showed the race in a statistical dead heat.
Braley has largely been viewed as the favorite in the race. The Cook Political Report still ranks the contest as Lean Democrat. The RealClearPolitics average gives Braley a 4.3 percentage-point advantage.
The Loras College poll, conducted from June 4 to 5, surveyed 600 likely voters. Its margin of error is 4 percentage points.
