Super Tuesday: Biden, Trump Head to Rematch; Schiff Helps Garvey Place in CA; AIPAC Suffers Setback

On Super Tuesday, millions of voters cast ballots in primaries across the United States, and we look at key contests in California, North Carolina, Arizona and elsewhere with American Prospect executive editor David Dayen. He says the California race to fill the seat of the late Senator Dianne Feinstein highlighted the ideological fight inside the Democratic Party, with centrist Congressmember Adam Schiff successfully boxing out his more progressive rivals by spending millions to elevate the profile of Republican candidate Steve Garvey. Both men are now headed to the general election, where Schiff is all but certain to win. It was quite successful," Dayen says of Schiff's strategy.
