I'm not familiar with AJC. Is this a reliable pollster?
Atlanta Journal-Constitution -- it's a good newspaper.
This poll is consistent with what we see with Georgia so far -- the state GOP may be pieces of work, but it knows how to win elections even with candidates disgusting to people who don't live in Georgia. Christian Protestant fundamentalism is strong in Georgia, and even if it has little to offer except Heaven to those who suffer in This World for corrupt politicians and rapacious plutocrats -- those people can't understand how Northern and Western secularists (or even religious people who can separate the Divine from something so profane as the economic well-being of one's family) can damn themselves to Hell.
It's a huge cultural divide, one that political campaigns cannot smooth.
