Tuesday 5 June 2012: 169 of 172 of California's delegates to the Republican National Convention are pledged to presidential contenders in today's California Presidential Primary.

• 159 district delegates are to be bound to presidential contenders based on the primary results in each of the 53 congressional districts: each congressional district is assigned 3 National Convention delegates and the presidential contender receiving the greatest number of votes in that district will receive all 3 of that district's National Convention delegates.
• 10 at-large delegates (10 base at-large delegates plus 0 bonus delegate) are to be bound to the presidential contender receiving the greatest number of votes in the primary statewide.

In addition, 3 party leaders, the National Committeeman, the National Committeewoman, and the chairman of the California's Republican Party, will attend the convention as unpledged delegates by virtue of their position.

The selection of Presidential Nominating Convention Delegates to the Republican National Convention ... shall be chosen by the Presidential candidate who obtained the plurality of Republican votes within each Congressional district, and, for ... at large ... by the Presidential candidate who obtained the plurality of Republican votes statewide. [Standing Rules and Bylaws of the California Republican Party As Amended 20 March 2011 Article VI Section 6.01 (A)]

Each delegate to the Republican National Convention shall use his or her best efforts at the convention for the party's presidential nominee candidate from California to whom the delegate has pledged support until the person is nominated for the office of President of the United States by the convention, receives less than 10 percent of the votes for nomination by the convention, releases the delegate from his or her obligation, or until two convention nominating ballots have been taken. Thereafter, each delegate shall be free to vote as he or she chooses.... [California Elections Code Section 6461.(c)]

Notes:

On 29 July 2011, California Governor Edmund G. "Jerry" Brown, Jr. signed AB80. The bill, introduced by Assembly Member Paul Fong (Democratic) on 3 January 2011, moves the Presidential Primary from the 1st Tuesday in February (7 February 2012) to the 1st Tuesday after the 1st Monday in June (5 June 2012), the same day as the statewide primary.

California Republican Party Chairman Ron Nehring today issued the following statement on 6 August 2010:

"Today the Republican National Committee took historic action to stop and reverse the trend to a national primary day. A national primary day, the result of more than 30 states - including California - moving their 2012 presidential primary to early February, would produce a nationalized primary contest that is television-centric, bypasses grassroots campaigning, and denies voters the proper vetting offered by a longer process. ... Under the rule just adopted, the California legislature will need to move the 2012 California presidential primary from the first Tuesday in February to no sooner than the first Tuesday in March. Because the California Republican Party and the California Democratic Party both allocate their national delegates by proportional representation, California will not need to move its primary to April or later, which would be the case if either party awarded delegates by winner-take-all.
