As for your remark on Bernie's principles: his principle while campaigning for HRC was preventing a Trump presidency. If you think that's wrong, even today, I have several bridges to sell you...

He got fucked by the DNC and HRC in 2016 and still toed the party line. You can't be fighting against the corrupt establishment and once it fuck you over, go on and support it because orange man bad. You are either against it or you're one of them. He showed his true colors then. Just another career politician.

He lost a lot of credibility right there and then.

I believe he would try for all he's worth. Will he succeed?

He won't succeed. He can't get all the Democrats in the Congress and the Senate on his side, let alone the Republicans. He would be a one term president that failed.
