Like the Senate race, the gubernatorial election in Florida is also close. The state hasnt elected a Democrat for governor for 24 years. Latest polls indicate the state's Agricultural Commissioner, Adam Puttnam, who had been leading the race for the GOP nomination, may be losing ground for siding with the NRA against Florida's new law raising the age for assault weapons to 21. Trump supporter Rep. Ron DeSantis leads him 2%. It has been close between the two since December. The Democrat primary is a knife-edge between Andrew Gillum and Philip Levine. A February poll showed Puttnam beating Levin 40-32, but even with Gillum in two polls, and ahead in two others. Gwen Graham was ahead of them in some earlier polls but has dropped to 9% in latest Gravis poll from 18% in December.
Florida GOP gubernatorial candidate dips in polls after supporting NRA | TheHill
In California the GOP have an uphill battle but the states multiparty "jungle primary" system has the top two going forward regardless of party, and with 6 Dem candidates and divisions between the Clinton and Bernie wings, the latest poll has the GOP candidate second in the jungle primary. 2 polls linked to State AG Gavin Newsom (D) as well as a Dem poll by PPP has John Cox (R) gaining ground but still behind him on 14-6%. Newsom is the likely to make the final 2 as he's on 28%. Surprisingly a poll in March 2018 found that in a Newsom vs Cox matchup it would be 45-45, though its a Republican pollster called Smithson. He opposes capital punishment, which might appeal to liberals. However California recently rejected a proposal to end the death penalty 53.15% to 46.85% (though in practice its meaningless because the appeals take decades there). Noone has been executed in the state since 2006.
NY is not competitive this time. Cuomo has two-to-one leads over all the potential Republican candidates. Likewise while we don't have polling, Hawaii is not considered competitive. In Connecticut Governor Dan Malloy was unpopular before Trump and as of February only has a 24% rating in the state, and has pushed controversial Sanctuary City policies. We have no polling yet, but Larry Sabato calls it a "toss up". Also hopefully for Republicans, the Dems in the state legislature are only 2% more popular than the GOP. Unfortunately for the GOP, Malloy is not running again this year.
