Is that so they could help obama win
I doubt it. I'd say it's more like a disgust over McCain. Illegals and our Mexico trade policies have shuttered quite a few N.C. plants. Those looking for work are competing with illegals who moved in to take what jobs didn't go overseas. North Carolina has been hurt pretty bad in the past decade by pro-Mexico and Pro-Illegal trade politics in Washington DC. McCain likely has few friends there in the middle class blue collar voters.
