Sen. Rob Portman (R-OH) announced Monday that he won’t seek reelection in 2022. One reason he chose to retire, he said in announcing his decision, is because “it has gotten harder and harder to break through the partisan gridlock and make progress on substantive policy.” But if Portman didn’t like partisan gridlock, he shouldn’t have spent years supporting it. Portman decries partisan gridlock after voting to keep it in place. A loyal Republican, Portman has been a reliable ally and backer of Mitch McConnell, his party’s leader in the Senate and a key architect of the Senate’s current dysfunction.
