Heller is the one Republican senator up for reelection in 2018 from a state that backed Hillary Clinton for president last year. Flake, who narrowly won a first term in an increasingly blue state, remains a target. Scott, who has hinted at a 2018 run, is perhaps the most threatening self-funder who might seek a seat held by a Democrat. And Cruz is being challenged by Rep. Beto O’Rourke (D), who’s seen as a long shot but has won fans in the national Democratic orbit.
“If Senators Heller, Flake and Cruz, along with Governor Scott, get their way, hard-working Americans will pay the price while insurance companies and the rich get a tax break,” DSCC spokesman David Bergstein said.
