OVERVIEW: The big day is here at last, and questions abound. Can Biden win a big victory and make himself the presumptive nominee? Can Sanders stay in it by winning California? What impact will Bloomberg’s commercials have? Can the others remain relevant?
THE PREDICTION: Biden wins virtually all of the states and becomes the clear leader, but it isn’t completely over. Sanders wins a narrow victory in California. The voters appreciate Bloomberg’s attacks on Trump, but they don’t vote for him. Warren drops out and endorses Sanders. Mayor Pete drops out and endorses Biden.
