Hillary at 43%. Her ceiling is in the mid-forties at best. Of course this race is winnable for Trump. Hillary is essentially the incumbent (the third term of Obama) yet she is mired in the low to mid-forties. There is no way Johnson and Stein are getting the percentages they are polling. They will be lucky to get 5% of the vote together.
Also, the incumbent party candidate of the two term president leaving office has their success linked in some ways to the outgoing president’s approval rating. In this poll it is 50-45 approval for Obama but, again, with Dem +14 over sample I would have to think his approval would be well under 50 with a more representative sample of maybe Dem +3 or so.
