On January 31, Congressman John Delaney of Maryland withdrew from the race for the Democratic presidential nomination.
Delaney had introduced a bill to impose a top-two system for the entire nation, for congressional races. He might have had a personal interest in promoting a top-two system. In November 2014, there were three candidates on the ballot in his Sixth District race. The results were: Delaney 94,704; the Republican nominee 91,930; Green Party nominee George Gluck 3,762. In a top-two system, Gluck would not have been on the ballot.
I wrote him several times about a top-two system, but he never answered my letters.
