^All of this.
Trump's best chance is actually twofold, IMO:
1) go after Hillary hard on WikiLeaks, emails, and corruption.
2) show a semblance of a human side.
Trump already has the "Lock Her Up!" voters and the Obama haters mostly locked up. What he (and many of his supporters) don't seem to understand is that's not enough to win the election. He has to pick up at least a few of the "moderate" voters. Not all of them, but a few. There are plenty of rich-white-soccer-moms in the suburbs of Philadelphia, Pittsburgh, Cleveland, etc who all hate Hillary because they think she's a shrew and she's an extension of Obama, and if he can give them an out, they're just dying to take it. To date he has shown an unwillingness or inability to reach that type of person.
