Sen. Joni Ernst (R-Iowa) on Tuesday announced her support for a bipartisan bill to lower drug prices, adding another GOP senator facing a competitive reelection race to the list of supporters.
Ernst endorsed a bill from fellow Iowan Sen. Chuck Grassley (R) and Sen. Ron Wyden (D-Ore.).
Sen. Martha McSally (R-Ariz.), who also faces a tough campaign this year, endorsed the bill last week, helping to add some momentum to the effort.
But the bill still faces tough prospects given that many Republican senators object to one of its key provisions, which would limit drug price increases in Medicare to the rate of inflation, denouncing it as a “price control.”
Senate Majority Leader Mitch McConnell (R-Ky.) acknowledged last week that Senate Republicans have “internal divisions” on the bill and declined to say whether it would get a vote.
There is also a question of whether Democrats would make a deal on one of their signature campaign issues when they are pushing for a stronger bill from House Democrats, which Republicans have widely dismissed.
Grassley is seeking to build support for his measure among Republicans by arguing it will help them keep control of the Senate this year by filling the need to act on a top issue for voters.
There are now roughly 12 announced GOP senators supporting the bill, and Grassley said last week he thinks he needs 25 to convince McConnell to allow a vote.
The White House has also announced its support for the bill, as President Trump seeks a victory on health care as well.
Sen. Susan Collins (R-Maine), also up for reelection this year, has endorsed the bill. Sens. Cory Gardner (R-Colo.) and Thom Tillis (R-N.C.), who face competitive races too, have so far declined to back it.
“At nearly every town hall or other stop I make on my 99 County Tour, and even in discussions around the kitchen table with my family members who depend on life-saving medications, Iowans from every corner of the state have made it clear that they want to see Congress address the skyrocketing cost of prescription drugs,” Ernst said in a statement.
Ernst on Tuesday also endorsed a more modest, GOP-only bill aimed at lowering drug prices led by Sen. Mike Crapo (R-Idaho).
Democrats said Ernst’s endorsement of Grassley’s bill was simply motivated by politics.
“Senator Ernst’s eleventh hour flip-flop to pretend she’s fighting to lower health care and prescription drug costs is an act of political desperation to salvage her career in Washington,” said Iowa Democratic Party spokesman Jeremy Busch.
