We might see a more diverse background in revolution leaders if people take it one step further and ignore the democratic process.

Sorry, who are those?

There is a level of endogamy in american politics which is spectacular, even by european standards.

The campaign raised much of its cash in small donations over the internet, with about half of its intake coming in increments of less than $200.[53] Both major party campaigns screened regularly for patterns of abuse and returned or rejected donations in excess of legal limits, from overseas, from untraceable addresses, or from fraudulent names

and his second campaign had 3 times larger user base.

You must not be very well versed in history then. That's pretty much where it always comes from.

Certainly many so-called "revolutions" are really just one group of elites fighting another, but "always" is just wrong. Do you think ISIS was formed by elites?

I have absolutely no idea. But I'd venture a wild guess and say there are probably a lot of Ba'ath Party people and ex-Saddam Hussein cronies running ISIS behind the scenes. Those people used to be "elites" back when Saddam ruled.

Not really, the Jacobins that were the main leaders of the French Revolution were elite politicians both from the formal aristocracy and the high ranks of the mercantile/intellectual class.

For example: free healthcare and college — great, that's what a civilized country should have... but while that reduces an economic burden on the poor, it also keeps dollars in the pockets of the rich and our tax system is so broken that it doesn't necessarily mean you can recover that money.

While much less appealing, Clinton's criticisms of Sanders for giving free college to the rich seems fundamentally rooted in the reality that while yes, eventually al“l of these things should be public services — but in the immediacy it's not really helpful to help everyone out the same amount because that's keeping everyone in the same place.

He's taken his fair share in corporate and special interest money e.g. agriculture, has a notable record of pork barreling for his home state, is one of the few candidates in recent history not to release a reasonable number of tax returns and his campaign has a very concerning amount of illegal donations.

Every candidate is incredibly weak and flawed this election including Bernie.
