Eisenhower, 1968 when it voted for Hubert Humphrey instead of Richard Nixon, and 2016 when it voted for Hillary Clinton instead of Donald Trump.

Trump's win in Merced county made it one of eight counties to flip from Biden to Trump, as well as making Merced one of five counties to vote for the Republican presidential candidate for the first time since George W. Bush in 2004. Democrat Barack Obama won a majority in the county in both 2008 and 2012. Before that, Republican George W. Bush won a majority in the county in both 2000 and 2004.
