This just in ... it looks like Cramer has changed his mind and will run against Heidkamp after all: https://www.sayanythingblog.com/entry/emineth-says-cramer-senate-race-withdraws-candidacy/
I couldn’t understand why he was hesitating on this to begin with. No reason for him not to upgrade to the Senate, given the weak Dem incumbent (he should’ve been the nominee in 2012 and freshman Rick Berg should’ve run for reelection to the House). Factoid: The GOP has not won this seat since Wild Bill Langer got his final victory in 1958. He died the following year and the Dems got the seat in 1960.
