Yep; a pole climber - so to speak. Just ask Willie Brown.
Willie Brown is still a significant player in this race. And just a few months ago, Brown wrote a little piece for the SF Chronicle saying Harass is disloyal.
My guess is if she gets close to the nomination, other politicians treated roughly by Harass will come out of the woodwork to stop her nomination. Or they will use a proxy like Tulsi to lower the boom on her.
