Millions of voters are heading to the polls today as 15 states are holding primaries and caucuses in what’s known as Super Tuesday. In California, there is a four-way race to fill the seat of the late Senator Dianne Feinstein. Three Democratic congressmembers Adam Schiff, Katie Porter and Barbara Lee are on the ballot along with Republican Steve Garvey, a former Major League Baseball player. The top two candidates, regardless of party, will face off in November.
