The group, Americans for Prosperity, is launching the $4 million ad campaign on Feb. 15 against Missouri Senator Claire McCaskill and Indiana Senator Joe Donnelly. “Joe Donnelly and Claire McCaskill promised tax reform for years but chose partisan politics over Indiana and Missouri families when they had a once-in-a-generation opportunity to provide tax relief. Americans deserve better, which is why AFP is committed to ensuring citizens see the pro-growth benefits of tax reform despite dismissals and deception from ‘no’ votes like Donnelly and McCaskill,” AFP President Tim Phillips said in a statement. Both ads tout the economic benefits of tax reform in Indiana and Missouri, and pointedly note that both Senators stood with Democratic leadership; the ads specifically call out Senate and House Minority Leaders Chuck Schumer and Nancy Pelosi. “Senator Claire McCaskill said she’d support tax cuts for hard working Missourians,” the ad against McCaskill states, “but when she had the chance, she said no, voting against tax cuts for you.” The Koch network had already invested $20 million in pushing for the passage of the tax reform bill, and had announced at its annual winter gathering in California last month that it was planning on spending an additional $20 million to sell it. In total, the politics and policy arm of the network could spend[ a record setting](http://time.com/5121930/koch-brothers-fall-elections/ "undefined") $400 million for the upcoming midterm elections. But the massive investment comes in a political environment that is highly unfavorable to Republicans. Even though Trump won Missouri and Indiana by almost 20 points, Democrats are expected to emerge as the victors in what could be a wave election, regaining control of the House of Representatives. The map is less favorable to the Democrats in the Senate, and the non-partisan Cook Political Report has rated McCaskill and Donnelly’s seats [as toss-ups.](https://www.cookpolitical.com/ratings/senate-race-ratings "undefined") But both candidates had significantly out-raised their potential Republican counterparts by the end of 2017, according to disclosure records from the Federal Election Commission. These are all factors that officials with the network have [openly acknowledged.](http://fortune.com/2018/01/29/koch-brothers-midterm-elections-2018/ "undefined") “These elections are going to be brutally tough,” Emily Seidel, Chief Executive Officer of Americans for Prosperity, said at the seminar last month. “We’ve never faced a challenge like this one.” _— With reporting by Phil Elliott_ (Disclosure: Time Inc., TIME’s parent company, has been acquired by Meredith Corp. in a deal partially financed by Koch Equity Development, a subsidiary of Koch Industries Inc.) ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5154530/koch-brothers-democrats-tax-reform/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5154530/koch-brothers-democrats-tax-reform/"},"headline":"A Koch Brothers Group Is Targeting These Democratic Senators for Voting Against Tax Reform","datePublished":"2018-02-13T10:00:48.000Z","dateModified":"2026-02-23T19:15:17.586Z","description":"Senators Claire McCaskill and Joe Donnelly are both up for tough reelection races","url":"https://time.com/5154530/koch-brothers-democrats-tax-reform/","keywords":["2018 Midterm Elections","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5fd82cdb9c014388/69892743e76ad294d163102a/claire-mccaskill-joe-donnelly.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alana Abramson","jobTitle":null,"url":"https://time.com/author/alana-abramson/"}],"articleSection":"Politics","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5fd82cdb9c014388/69892743e76ad294d163102a/claire-mccaskill-joe-donnelly.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"claire-mccaskill-joe-donnelly","caption":"Sen.
