Still, DNC pledged delegates have traditionally been divvied up by population and by how well Democratic presidential nominees performed in each state in the last three presidential elections. Though the 2020 race is too far off to predict how California's move would alter the dynamics, Democratic operatives and party members in California said a few changes seem certain. Other than that race, though, California Democrats have had little influence on the Democratic nomination since Robert Kennedy was killed at the Ambassador Hotel in Los Angeles following his 1968 Democratic primary victory there. It’s unclear if the Democratic majority in Sacramento has thought through the potential effects of moving California’s Democratic and Republican primaries from late in the election calendar to right after Iowa, New Hampshire, Nevada and South Carolina.

California's argument: The state has taken a leading role in the Democratic resistance

(CNN) California is poised to make a big move up in the primary calendar -- dramatically changing the dynamics of a 2020 race now in its earliest stages. The last time California went early — when it was one of many states holding primaries on Feb. 5, 2008 — Hillary Clinton won here but lost the Democratic nomination to Barack Obama.
California wants to schedule its primaries earlier than usual, possibly on March or Super Tuesday, to have much more influence in comparison to its weight and diversity and to help Californian candidates, such as Eric Garcetti and Kamala Harris.
