Democratic Candidates should be inspiring that enthusiasm from people that will actually vote. Sanders got the same support that Ron Paul did, for the same reasons. Once he got out of Caucuses, he didn't have too much success.
Clinton was the candidate from very early on. She had the record, the experience, and the support. Sanders was a Democrat because of convenience, acted like he deserved something because of it, and the only reason he had a chance was because Hillary didn't attack him at all, something the Republicans were salivating for.
If you really think a outspoken socialist that praised Castro and breadlines that wrote off the South, has no idea what math is, and had no actual plans for any of his ideas beyond having people rally around congress protesting had any shot at the Presidency in a country where Donald Trump just won, I've got many bridges to sell you. I'd put money on him losing against Trump in 2020. It had nothing to do with conspiracy why the DNC didn't support him, it was that he was a far worse candidate that had nothing to do with the party. Hopefully history repeats itself when it comes to him, except for him staying in the primary months after he was mathmatically eliminated.
Fuck Sanders. Let him fade away in Vermont where he can collect dust and fail to get more of his supported candidates in office.
