The people who seek an excuse to dump on Harris some more, obviously don't remember that the AG race started with Cooley as the favorite. Her win was actually a moderate upset.
This was my first midterm I paid any attention to so:
Cooley was only the favorite insofar as he could keep the race competitive and Harris was already polarizing. It was still never truly his to win just because of partisan leanings, unless all cards fell into place. They didn't.
No different from Mark Udall vs. Cory Gardner, except that Harris actually campaigned seriously.
