My apologies for the time lag in response! I don’t actually log in much to check pings.
Christina is a dyed-in-the-wool conservative that the establishment see as a direct threat. And the Dems HATE her passionately. Her father was State Rep as well for the same district,and he was conservative too.
Fwiw, Hagan’s opponent Gonzalez is a nice guy and former tOSU football player. He also has the complete support of the Kasich establishment, which is damning praise indeed. There is a third candidate who has zero chance of winning but a decent chance if costing Christina the race.
