Seven states are holding their primaries tonight. Many of the most notable contests will be conducted using California’s top-two primary rules, under which the two contenders with the most votes, regardless of party, will advance to the Nov. 8 general election. Candidates cannot win outright tonight by taking a majority of the vote except in special elections and some officially nonpartisan elections.
