racists
misogynists
women haters

As a woman I especially resent the charge of misogyny and woman hating. As a feminist I also deeply resent being assimilated to the category of "Bernie bros." I want my own pejorative term, but "Bernie sistahs" just doesn't seem to carry the same level of dismissive contempt. I feel left out!

But I am not sure that it is insulting enough. Maybe we could have a poll of male DUers to test it?

but I don't really feel comfortable with insulting you!

You're a good guy!

Being a Bernie Bro is bad, but, as I understand Clintonite theology, we aren't necessarily going to Hell, the way you are.

Contemplating that difference, now I feel left out.

It's really tough, isn't it, to win the prize for the most derogatory description? But don't give up, I am sure if you put your mind to it, you can come up with something equally bad for your sex. After all, we're all in this together!

The name-calling on both sides has become silly on steroids.

Bill Clinton said that. They don't need our votes, and they ain't getting it.

Dreamers
Unicorns

Let's have both: unicorn dreamers.

Groovy!

They yell out grade school level insults because they have nothing but a corrupt candidate.

a Clinton fan referred to us as "teenagers" and Bernie as "grumpy grandpa" .

(and proud) gasp..

ugliness.

"you clowns"

That's one I've seen.

Losers and whiners

Well, that's what they called Bernie.

Hippies
Millennials (or as Hillary says "the young people&quot
Dreamers

are true, and fair game for a political campaign, where fitness to lead is at issue. Hillarians seem to have a very thin skin considering that she wants to run the country. She should address the questions instead of hiding entire plicy areas completely. (Like the ultra-controversial global privatization deal, WTO GATS)

back in February that implied that Bernie Sanders supporters were like the Red Guard during the Cultural Revolution in China.

Yes you read that right,figurative gang rapists. There is in article in The Guardian in which a Clinton supporter caled Sanders supporters gang rapists.
Edit: I am posting the quote just in case people think I am trolling.

There's "unhinged", which escalated to "more unhinged than usual", or the parlay "weird and unhinged".

Such Sanders supporters can be spotted "at his rallies of low-information political naifs."

If Hillary wins the nomination, those of us who intend to hold our noses and vote for her will, nevertheless, remember these and other gems from your list. I'm thinking about a sig line: "Low-information political naifs for Clinton!"

I will vote for Hillary is she wins the nomination, but after all the insults from her and her supporters she will not get one dime from me, and I will not volunteer for her. We keep hearing about the Bernie Bros, but noting about the constant insults from the Hillary supporters. The media protects them. There is a key difference between Bernie Sanders supporters and Hillary supporters I noticed across websites. Bernie Sanders supporters are focused on Hillary Clinton, I rarely notice them attacking Hillary supporters, while Hillary supporters attack Bernie supporters all the time.

"There's a reason we were fine with such people not voting: because they're terrible human beings." (from this post in the Clinton group, emphasis added)

To be fair to the Clinton supporters, though, one of them did point out what was, to my mind, a fairly obvious reaction to the charge. The subject of the thread was the judicial election in Wisconsin, in which some of the voters in each party's primary voted for a Presidential candidate but skipped that downticket race. The HCG was aflame because, according to exit polls, "only" 85% of the Sanders voters also voted on the judgeship. Kudos to kjones, with hopes that s/he doesn't get blocked from the group for making this observation:

came out to vote for Cruz & Trump did.

It amazes me the lack of critical thinking from some people. And this isn't even hard to understand.

I suspect that Democratic turnout was suppressed partly because of the reiterated insistence from the Clinton camp that Sanders has absolutely no chance, math math math, etc. If the widespread perception is that one party's race is effectively over while the other party still has a real contest going, then it will skew the turnout. Wisconsin should have postponed the judicial election to November.

My vague recollection is that, back in the day when the Voting Rights Act required preclearance for certain things, New York City was denied permission to make such a pairing. The primaries for special elections in a couple of City Council districts couldn't be held on the same day as a city-wide referendum, because turnout in those districts would have been disproportionately high. You're right, this isn't hard to understand.
