Yes, he could blow her out in New York and California.
Her delegate lead is ~210. After tonight, it could be more like ~250 if she gets big margins in FL and NC and loses narrowly in the north. With blowout wins in the upcoming lily white caucus states, he can cut her delegate lead down by about 100. Can he then make up 150 delegates in the remaining states, including New York, Pennsylvania, and California? Certainly.
He has a superior message, superior volunteer effort, superior fundraising -- his campaign in superior in every way (except the candidate, but that's just my personal O). Yet despite this, he still gets to keep the underdog aura due to his delegate deficit. So the longer it goes on, the more he rolls.
Btw, Hillary's wins so far have been based on her name reputation and running out the clock. If you had put these dynamics in Alabama and just let it marinate for 8 months, Bernie could have absolutely flipped the state.
Just wait until tomorrow before you start making these threads Beet.
