U.S. Sen. Ed Markey secured the Democratic nomination in Massachusetts’ Senate primary Tuesday, once again fending off a push for generational change as he seeks a third term.

Markey, 80, defeated U.S. Rep. Seth Moulton, 47, who had attempted to argue that it was time to do away with the “status quo” in his pursuit to oust the octogenarian.

Yet Markey successfully pointed to Moulton’s more moderate positions to argue that it was Moulton — not the older incumbent — who was out of touch with the state’s voters. Perhaps no other issue defined the race more than transgender rights, and Markey repeatedly hit Moulton for previously saying he would not want his daughters to play against transgender athletes.
