The caucus system is a mis-representative joke. I know Bernie likes it 'cuz he does best when the actual people aren't actually voting, (caucuses are the only reason he stayed in the race at all in 2016), but it's a ridiculous sham that should be done away with... and never should have existed in the first place. While we're doing election reform, that's the first place to start. It's fan-club bullshit that's open to endless hijinks and it's no way to be picking a nominee.
And while we're at it, superdelegates need to go, too. And the electoral college.
