Americans for Prosperity is launching a new, more than $300,000 buy focused on prodding vulnerable Democratic senators to work with Republicans on tax reform, according to officials at the outfit.

The conservative group is going to target a slate of Democrats up for reelection, including senators like Claire McCaskill of Missouri, Sherrod Brown of Ohio and Bill Nelson of Florida, Joe Manchin of West Virginia, Heidi Heitkamp of North Dakota and Joe Donnelly of Indiana.


The group says it's using the ads to push the senators to share AFP's tax reform principles, which include advocating simple broad based rate reductions that induce growth. But since Republicans are aiming at passing tax reform by the party-line reconciliation mechanism, the ads will also serve to highlight that Democrats are on the outside looking in at the process and that a Republican senator will have more sway under a GOP Senate.

"We’ll continue to invest and mobilize our grassroots infrastructure to show lawmakers the support that’s out there for these principles," said AFP President Tim Phillips.

The ads will run on digital platforms and is the beginning of a seven-figure tax reform push by AFP this summer. AFP is also expected to spend money on door-knocking and direct mail.
