Dem primary system is what the rank and file demand. Start doing a winner take all and watch the fur fly when someone wins California by 5 votes but is entitled to ALL of its delegates. I like the recent reforms starting with getting rid of caucuses for primaries which is the best way to boost participation. Yeah yeah the whole Iowa and NH go first thing is annoying but as long as those two remain swing states nobody is going to PO its voters over that.
Regarding Biden, he's had far, far more staying power thus far than I thought he would. But, you'd be a fool to dismiss his chances. He's got two big things going for him: 1) Nobody has staked a claim to non-white voters yet (looking at you Harris or O'Rourke) while he's wearing the Obama mantle with them at this point. That could end up being decisive. 2) Don't dismiss a "Return to Normalcy" sentiment amongst the electorate either.
My personal view on Uncle Joe is this. I don't worry about him in a debate after he ate media darling Weasel Paul Ryan alive in 2012. He's not nearly as progressive as my choice Lizzy Warren, but I don't picture him vetoing progressive legislation either. If a Dem congress puts tax hikes for the rich and expanded Medicare on his desk, he'll sign it. The hurdle to get any of these things passed into law would never be a Joe Biden Presidency. It'll be convincing the Dems sitting in marginal seats (Tester, Manchin, etc).
