The letter urges Tennessee’s incumbent Republican senator, the proudly moderate Lamar Alexander, to forego the rigors of another campaign and retire with dignity, or, as the media puts it, face a challenge from “the Right.”

The portion of the letter which has received the most attention reads: “During your tenure in the Senate we have no doubt that you voted in a way which you felt was appropriate. Unfortunately, our great nation can no longer afford compromise and bipartisanship, two traits for which you have become famous. America faces serious challenges and needs policymakers who will defend conservative values, not work with those who are actively undermining those values.”

I was the one who suggested this particular passage in the letter.
