What did OBAMA do differently in '08 from Hillary in 2016?

At the time, I did not see a lot of difference between the two on policy--apart from Obama being opposed to the Iraq War and Hillary supporting it.

And since Obama had less of a record, it was easier to project our hopes onto him.

On the war issue, Hillary seemed more belligerent than Trump, at least when it came to Russia, and her record as secretary of state and recently consorting with neocons seemed imply she would be looking for more fights than Obama was.

That may not have been the best way to excite the base of the Democratic Party, and may even have given pause to some swing voters.

EDIT: How about POLICY differences? Or at least perceived ones at the time.
