It really is a cluster, and breaking perfectly for Bernie. If the more moderate Dems would just pick one of them to run, they'd steamroll Bernie. He'll pick up ~30% of the vote regardless, and if there's one "moderate" running he'll lose 70-30, but if there are 3, he'll win 30-25-25-20 or whatever.
The debates have been awesome though, must see TV. Pete's comment of being the only non-millionaire/billionaire on stage lands every time he drops it. You can see Bernie shudder when it gets pointed out that he is indeed in the top 5%. Even Bloomie got in on it pointing out the Bernie has 3 houses. That was before Warren just single-handedly ended his campaign. The debates are the best reality show on TV right now.
