The question for Republicans is who is going to run for U.S. Senate this year. A pair of Republicans have counted themselves out of running, which only adds to an already long list. State Assemblyman Jon Bramnick and state Sen. Michael Doherty were the latest to say they aren’t going to challenge Cory Booker in his reelection bid. Booker won last year but it was an unexpired term and must run again this year.
