Smith is also apparently good friends with Joe Biden, and I wouldn't be surprised to see Biden come down to SC to campaign with him.
I think this will be the sleeper race of the year. If the Dems have an exceptionally good year in gubernatorial races (like the GOP did in 2014), I think this domino will definitely fall, and probably before states like KS and OK.
I can’t remember a time when this many incumbent governors were struggling so much. AZ, IA, IL, WI, AK, HI, KS, RI, SC are all pretty vulnerable either in generals or primaries. And Hogan might lose anyway just because he’s in such a blue inelastic state. Only one incumbent lost in the 2006 wave. 3 in 2014. 2 in 2010.
It's sort of infuriating that Democrats would have an outside shot at taking every governorship on the Eastern Seaboard were it not for, of all states, Massachusetts.
