I think you're right. After almost evening the odds in the last couple weeks, Clinton's numbers have begun to pick up a little. The debates will seal the fate of whichever candidate is destined to win.
In theory, that would be Clinton, as it seems Trump really has little to offer beyond empty platitudes and red meat for his base.
Republicans, however have pretty much rallied behind him at this point though and I can't really say the same for Democrats in regards to Clinton.
