Don't forget to adjust for the rigged ballot machines, the hanging chads, and the cemetery vote; they usually goes strongly for the Demonicrat candidate.
Yes, democrat vote fraud is always a problem. But it will be mitigated somewhat this year by the new wave of voter ID laws which have been implemented in many states, including my own, NC. For the first time since I have lived here, I was required to show a picture ID when I voted in the primary earlier this year.
Of course, this will achieve nothing if the voting machines themselves are rigged. But rigging will be more difficult in states where the voting apparatus is controlled by republicans. I'll wager that Trump is well aware of this matter.
