California voters chose 55 electors, the most out of any state, to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan.

According to Secretary of State Debra Bowen's website, the President won the popular vote with 60.24%, with Mitt Romney in second place at 37.12%, and Libertarian candidate Gary Johnson in third at 1.10%.

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 primary was non-binding, and took place after Gary Johnson had already won the Libertarian nomination at the Party's 2012 convention.

The American Independent Party, a far-right and paleoconservative political party that formed when endorsing the candidacy of George Wallace in 1968 held a small presidential primary on June 5.
