The conservative Americans for Prosperity is spending nearly $5 million on ads in three Senate races, including two seats that Republicans are trying to flip and one the GOP is defending.
The Koch brothers-backed group is launching television and digital ads against Democratic Sens. Tammy Baldwin of Wisconsin and Claire McCaskill of Missouri, and former Tennessee Gov. Phil Bredesen, who is running for Senate.
The ads will run on broadcast and cable networks from from Aug. 30 through Sept. 16, and they hit the Democrats on separate issues.
Americans for Prosperity targets Baldwin on taxes, and supports state Sen. Leah Vukmir who won the GOP nomination earlier this month. The group is spending $820,000 on the Wisconsin ads. Inside Elections with Nathan L. Gonzales rates the Wisconsin Senate race Lean Democratic.
In Missouri, the group is spending $2.1 million on 30-second spot that labels McCaskill a “career politician” and touches on a couple issues that have grabbed headlines in the race. McCaskill is facing state Attorney General Josh Hawley in a race that Inside Elections rates a Toss-up.
Republicans are defending a Senate seat in Tennessee, where two-term GOP Sen. Bob Corker is retiring. Republican Rep. Marsha Blackburn faces Bredesen in a race that Inside Elections rates Lean Republican.
Americans for Prosperity is spending $2 million on a television and digital ad knocking Bredesen for spending to improve the governor’s mansion while in office.
