Zuckerburg is not really that well known and as you say, not very charismatic.
I certainly agree that dark horse candidates can come out of nowhere, I just don't think that Zuckerburg is one of them.
also, its occasionally a valuable reference when talking politics, for instance: comey was fired and lots of people tried to say this was normal and expected, but there was a market that had being fbi director on 6/30 at 95%. pretty much throws cold water on that theory. not that it was anything other than an obvious deflection to begin with, but still kind of interesting.
i encourage you to follow the political futures markets, its a worthwhile endeavor. predictit.com is the standard now that intrade died. my apologies if you are actually speaking from some greater experience though.
What is it you think I'm doing?
I didn't really think Trump would get the R nomination, that's true. I don't see how that informs the comparison to Zuckerburg.
