The National Education Association will start airing a new ad Tuesday attacking Joni Ernst on education.
The ad, provided first to CQ Roll Call, features voters speaking directly to camera as a narrator attacks Ernst's record on education.
"Joni Ernst is leading the fight to take funding from public school students and give it to wealthy private schools instead," a male narrator says. "Ernst would eliminate the Department of Education, cutting almost a billion dollars from Iowa schools and putting college out of reach," he ads.
"Joni Ernst just isn't someone we can trust," a woman says at the close of the ad.
The ad will run through Nov. 3 in the Davenport and Des Moines media markets, according to an NEA spokesman. The buy is just more than $500,000. Ernst faces Rep. Bruce Braley, D-Iowa, in the nail-biter race for the open seat currently held by Sen. Tom Harkin, D-Iowa, who is retiring.
Polls show a tight race, and the result could decide which party controls the Senate. Republicans need to gain a net of six seats to wrest control of the chamber from Democrats.
The race is rated Tossup by the Rothenberg Political Report/Roll Call.
