CONCORD, N.H. — When Fox News called John Kasich’s second-place finish in New Hampshire at 9 p.m. on Tuesday night, a fairly sedate cheer went up from the crowd gathered at the primary night party in a Marriott conference room here. People dressed in outdoor vests milled around drinking white wine and occasionally engaging in an “O-H-I-O” chant, but mostly politely biding time until their man from Westerville, Ohio, showed up.
