The politics of Los Angeles County leans Democratic. Los Angeles County has voted Democratic in every Presidential election since 1988, with every Democratic nominee winning the county by a margin of at least 25 points since 1992. Los Angeles County has voted for the Democratic candidate in most of the presidential elections in the past four decades, although it did vote twice for Dwight Eisenhower (1952, 1956), Richard Nixon (1968, 1972), and Ronald Reagan (1980, 1984), the latter two of whom were Californians. From 1920 to 1984 it could be considered as a reliable bellwether county which always voted for the eventual national winner. Los Angeles went against the overall national picture in 1988, 2000, 2004 and 2016.
Northern Los Angeles County, which includes the cities of Santa Clarita, Lancaster, and Palmdale, has historically been a Republican stronghold, but has been shifting Democratic in recent elections. All three cities voted for Hillary Clinton in 2016 and Joe Biden in 2020. The region is represented in the House of Representatives by Republicans Mike Garcia and Jay Obernolte. The region currently leans Democratic in presidential elections, but less so than the rest of the county.
