By today 24 had responded. Of those 24, 15 supported Obama, 6 supported Romney, 2 were undecided but leaning toward Obama, and 1 refused to answer. So by this measure at least, the leaders of the startup community favor Obama by more than 2 to 1.
I can’t say who I asked, since I promised not to, but the list was pretty much the usual suspects: the most prominent founders and investors. Most of the people I asked live in Silicon Valley, but a handful don’t. I didn’t include myself in the survey, but I prefer Obama too.
