The Democratic Senate Majority PAC is tying Iowa Senate candidate Joni Ernst (R) to Charles and David Koch in a new ad, the group's latest attempt to get voters to distrust her campaign.
The ad is the latest in a flurry of Democratic attacks following acknowledgement of a tight race in Iowa. Rep. Bruce Braley (D-Iowa), her Democratic opponent, has made some missteps in the race, and if Republicans can pick off this open seat, their path to the Senate majority would be considerably easier.
The race is just getting underway following Ernst's midsummer primary win, unlike many other Senate battles where both sides have been on the air for months. Recent polling shows a coin-flip race.
