HELL NO!
The only reason I like Sanders so much is his great true progressive left policy (that he actually means) and his unwavering commitment thereto for the past 5-odd decades. It's sad how many people voted 'Yes'.
I also still take exception to the word 'fans'.
I think you may have misread the question. I read it not as asking whether you would vote for a conservative sanders or not, it's asking whether or not you would approve of his tactics if he was someone you didn't agree with ideologically.
