Rep. Richard Neal, the chairman of the powerful Ways and Means Committee, has staved off a primary challenge for his US House seat in Massachusetts, following the concession Tuesday night of Holyoke, Massachusetts, Mayor Alex Morse.

“I just want to start off by congratulating congressman Richard Neal on winning his reelection tonight,” Morse told supporters Tuesday evening. “But I also want to make it very clear how incredibly proud I am of what we fought for over the last 14 months.”

Winning his current job as Holyoke mayor straight out of college in 2011, Morse supports “Medicare for All” and
