Clinton has already basically locked down 270 electors. She doesn't need to do anymore than that to win the presidency but she likely will. She is within striking distance in NV, NC, FL, and AZ. Trump is within striking distance in Maine. Even if he picks up a couple of Maine's electors(Maine splits their electors) Clinton would still win.
I agree she has the edge but it is narrowing. FL, NV, AZ, GA and NC have all moved his way the last week.
