Sanders congratulated Biden on his first win and said it was nothing for his own supporters to worry about.

“That will not be the only defeat. A lot of states in this country. Nobody wins them all,” he told a cheering crowd in Virginia. “Now we enter Super Tuesday.”

Sanders supporters are all hoping so :p

Pressure is building on lower performing candidates including former South Bend, Indiana, Mayor Pete Buttigieg, Minnesota Sen. Amy Klobuchar and Massachusetts Sen. Elizabeth Warren to justify staying in the race. None gave any indication on Saturday that they would exit before Tuesday.

I can't tell if these candidates are helping Sanders by staying in the race and splitting the moderate vote or hurting him by making it more likely a contested convention is possible in order for superdelegates to give a moderate the victory.

Even with the victory, the shortcomings of Biden’s campaign remain, including a lack of robust funding and organization, and he will face for the first time Mike Bloomberg, a billionaire who has spent more than $500 million advertising in the Super Tuesday states. Bloomberg announced his own plan to deliver a three-minute prime-time address Sunday night on two television networks. He didn’t say how much he paid for the air time, which is unprecedented in recent decades.

Given his much better debate performance in the last debate and the sheer amount of money he has, it's pretty likely this will work, regardless of the potential costs.
