I don't know if that's the consensus, but I think without a strong candidate who brings his or her own message to the table, the party flounders. The party wanted Hillary in 2008. They got Obama because the voters liked him. The party wanted Hillary in 2016, and didn't see the support for Bernie coming, nor the backlash to what appeared to be a rigged system.
Now, what is the party's message? Free health care? Student loan forgiveness? Everyone I know only cares about getting Trump out, but that's not the message. We have a muddled mess of entitlements instead. Biden seemed like the guy that could run on being moderate and beating Trump, but he seems like he's losing it. Once the nominee is set, there should be some unity of message, but for right now the stupid debates with a dozen people on stage at once are a pretty good demonstration of where the party seems to be.
