They bloody well should be. Even the MSM had to report on the fact that Clinton and the DNC conspired to make sure Bernie didn't win the primary, which is exactly what Bernie supporters had been saying from the start (and were mocked for saying until the emails leaked and proved them right)
Well let's remember that Bernie was sleeping on a friend's couch until he ran for prez and now owns three houses, the last one $600,000, paid for by the Klintons. Pretty good for a guy who wants everything free for everyone. It was a set up from the start that went horribly wrong for Billary and she had to pull the plug on him.
Do you have a source for that? Fact Check: Did Bernie Sanders accept payment for endorsement of Hillary Clinton?
Again, a rumor unconfirmed, and apparently disproved, see above. You may not like Snopes, but there are others. (I, for one, don't trust any single source for or against. Double check everything.)
... so... no one else is a little concerned about this blatant violation of the constitution? I know this is an old story that happened back in April 11th but this is the first I'm hearing about it.
I cannot speak for anyone else, but I am NOT concerned about a rumor that's been proven wrong to my satisfaction. Your mileage may vary if you do your own due diligence.
Actually, I believe that the "sleeping on a friend's couch" was until he was elected to Congress...I'm pretty sure he did much better once he was on the public payroll.
