In California, Douglas Democrats hold their state convention in Sacramento and choose electors
With the Democrats of California irrevocably split, the Douglas Democratic state convention assembled at the the Sixth Street Methodist Episcopal Church in Sacramento. The 359 delegates endorsed the Douglas ticket and the national platform passed in Baltimore, and nominated four state electors. They also condemned the withdrawals at the national conventions that had resulted in the alternative nomination of Breckinridge. (By John Osborne)
