Bill Clinton, (bless his heart) thinks that he can denigrate Trump supporters by calling them rednecks.
You see, I don't take that as an insult. The rednecks I know are hard-working, family-loving, God-fearing, school-supporting, community-volunteering types who want to raise their families, work at their jobs, and live free. Rednecks are salt of the earth people who hunt, fish, shoot, trap, and don't want to bother anyone.
Bill Clinton, on the other hand, is a woman-abusing, skirt-chasing, influence-peddling, career politician. If he didn't have Secret Service protection, he'd probably be getting his ass whipped fairly regularly.
He must feel pretty confident about Hillary's chances if he can afford to insult the working class. What an asshole.
