It is Election Eve in California, as millions of voters go to the polls tomorrow, or have already cast their ballots, in the state’s primary. There is a hotly contested U.S. Senate campaign, as well as some key races for swing district Congressional seats.

For more on tomorrow’s primary, part of Super Tuesday across the country, KCBS Radio news anchors Bret Burkhart and Patti Reising were joined by KCBS political reporter Doug Sovern and Mike Madrid, longtime California Republican strategist based in Sacramento. Madrid was among those who founded the anti-Trump Lincoln Project, and is a leader of the political communications firm Grassroots Lab.
