She only recently did an anti-TPP U-turn - who knows what she stands for after being elected. Fortunately for us she won't be elected though!
What's going to happen with this election is anyone's guess IMO. It could be Trump vs. Clinton, in which case Clinton will likely win (lower unfavorability). Or it could be Cruz vs. Clinton, which again probably favors Clinton (IMO, Cruz is far more dangerous than Trump, but that's my opinion). Or, we could get a brokered GOP convention and Kasich could get the nomination, and in a Kasich vs. Clinton fight, Kasich will likely win. Or, Kasich could get the nomination, Trump could run as an independent splitting the ticket, and who knows who'll win, though likely it'll again be Hillary because Trump/Kasich will split the GOP voters. Or Bernie could change his mind and run as an independent since the DNC has screwed him over so much, making a 3-way or 4-way race with a completely unpredictable outcome (though it might end up with the House of Representatives making the decision).
Trump and Clinton have been tied in national polls recently (there was even an outlier showing +3 Trump) and this is before he has started attacking her and before any debates. She's going down.
What makes you think that?
At this point I don't see a way for her to lose, unfortunately.
