Yeah Sanders Campaign was on a downhill slide since Super Tuesday, and it only got steeper after New York. The past two days with this, the DNC shenanigans and the HORRIBLE interview it feels like it's a full on crash and bern.
To not sound like a parrot, I started off really liking Sanders, thinking he did a good job trying to pull Hillary left and make the word Socialism less toxic (ignoring he's actually a Social Democrat).
As the campaign progressed more and more I disliked him more and more. It's not like he even got an inflated ego from doing better than he expected, although that may have been a part. I suspect that it is because Presidential campaigns will bring out who you really are, from your past and the way you act in a campaign. I certainly don't want someone like Sanders in the White House, and while I'm not Clinton's hugest fan, she's leagues better than him.
