That "contested convention" thing? Rubbish.

[geek tragedy]

11. Here's what Bernie would lose:

1) his speaking slot at the convention;
2) input into party platform;
3) input into reforming party election rules
4) his reputation (he'd be Glenn Close from Fatal Attraction "I'm not going to be ignored" combined Lloyd from Dumb and Dumber "so you're telling me there's a chance."

People would start questioning his mental state if he lost the election and pretended otherwise, with people pointedly questioning why the first woman to win a major party's presidential nomination would also be the first one to face a challenge despite having such an overwhelming victory in the voting.

It would make Sanders look like a narcissistic vanity candidate and toxic third party saboteur, and that's exactly how he would be treated.
