Hillary is running as the incumbent. She is betting voters crave stability and competence so running for the third Obama term is her ace card.
What if they really want change? That’s where she’s vulnerable.
Hillary benefits from the sort of thing Obama had going for him in 2008, only this time it’s gender instead of race. Otherwise sensible people think it would be nice to vote for a woman, and not nice to vote against her. That’s good for an extra 5% going in. Trump just has to pound away at the “yes, but not this woman” message.
Unless people have just given up on getting any change. If she gets elected the war against America will ramp up.
