He beat Strickland in a recession year. Last year, he was uncontested in a governor contest. And he made remarks that stated he clearly is against health care for the poor, a natl health care, but clearly is looking to expand medicaid, a state law.
While he by far outclasses Jeb, Hilary is still strong against GOP.
Strickland's competitive in polls against Portman, so it was pretty impressive that Kasich beat him when he was an incumbent.
Incumbent Governors also tend not to suffer in wave years the way Senators do. 2010 saw Beebe reelected in Arkansas, and John Lynch reelected in New Hampshire. 2006 saw Republicans reelected in California, Rhode Island, Connecticut, Hawaii, Minnesota and Vermont.
