12% because I want bragging right since everyone else is saying 8%.

right now it's expected that she'll get 46% of the vote while trump will get 34%. Gary Johnson will get 9% (while it looks like his supporters are starting to vote Hillary) . Jill stein will get 3% (while voters of her are likely to flip voting to hillary) 4% are still undecided.
my guess:
Hillary: 51%
Donald: 37%
Gary Johnson: 8%
Jill: 4%
