If Hillary is +7 nationally, I dont know why she's +2 or 3 in BG states. Remember in 2012 when national polls showing Mittens leading Obama? Black mamba showed they were bunk because they heavily weighted south, a traditionally strong GOP region. I hope nothing of the sort is happening with Hillary.
Trump's probably not leading by much in the South if he's getting crushed in Virginia, losing florida, is down slightly in NC, and the gap between him and hilary is under 10 points in Texas, SC and GA. Racking up huge leads in OK, AL,LA and etc won't help him win the south by a ton.
