A predominantly suburban county, Jefferson County used to be fairly independent-leaning at the federal level with a tendency to tilt Democratic. Presidential elections in Jefferson County were often very close; George W. Bush just narrowly carried the county in 2004 by less than 600 votes and by just over a half of a percentage point. Al Gore and Barack Obama also just narrowly carried the county in 2000 and 2008, respectively. Bill Clinton, however, did manage to carry Jefferson County by double digits both times in 1992 and 1996. However, in 2012 the county, in line with the state as a whole, began to swing hard to the right with Mitt Romney carrying it with 55% of the vote. In 2016 Donald Trump won the county with 65% of the vote, the largest margin of any candidate since Lyndon Johnson in 1964.

Typical of the suburban culture in most counties throughout the country, voters in Jefferson County tend to be rather centrist on social issues but more liberal on economic issues. In 2004, Missourians voted on a constitutional amendment to define marriage as the union between a man and a woman—it overwhelmingly passed Jefferson County with 72.56 percent of the vote. The initiative passed the state with 71 percent of support from voters as Missouri became the first state to ban same-sex marriage. In 2006, Missourians voted on a constitutional amendment to fund and legalize embryonic stem cell research in the state—it narrowly passed Jefferson County with 51.85 percent voting for the measure. The initiative narrowly passed the state with 51 percent of support from voters as Missouri became one of the first states in the nation to approve embryonic stem cell research. In 2006, Missourians voted on a proposition (Proposition B) to increase the minimum wage in the state to $6.50 an hour—it passed Jefferson County with 79.90 percent of the vote. The proposition strongly passed every single county in Missouri with 78.99 percent voting in favor as the minimum wage was increased to $6.50 an hour in the state. During the same election, voters in five other states also strongly approved increases in the minimum wage.

2008 Missouri presidential primary

Republican

U.S. Senator John McCain (R-Arizona) won Jefferson County with 33.54% of the vote. Former Governor Mitt Romney (R-Massachusetts finished in second with 30.45% of the vote, while former Governor Mike Huckabee (R-Arkansas) came in third with 30.19% in Jefferson County. Libertarian-leaning U.S. Representative Ron Paul (R-Texas) finished a distant fourth place with 3.94% of the vote in Jefferson County. McCain received all of Missouri's 58 delegates as the Republican Party utilizes the winner-takes-all system.

Democratic

U.S. Senator Hillary Clinton (D-New York) won Jefferson County over Senator Barack Obama (D-Illinois) with 61.32% of the vote, while Obama received 35.02% of the vote. Although he withdrew from the race, former U.S. Senator John Edwards (D-North Carolina) still received 2.74% of the vote in Jefferson County. Jefferson County gave Clinton one of her strongest showings in a predominantly suburban county in the entire country.

Clinton had a large initial lead in Missouri at the beginning of the evening as the rural precincts began to report, leading several news organizations to call the state for her; however, Obama rallied from behind as the heavily African American precincts from St. Louis began to report and eventually put him over the top. In the end, Obama received 49.32 percent of the vote to Clinton's 47.90% — a 1.42% difference. Both candidates split Missouri's 72 delegates, as the Democratic Party utilizes proportional representation.

Hillary Rodham Clinton received more votes, a total of 19,075, than any candidate from either party in Jefferson County during the 2008 Missouri Presidential Primaries. She also received more votes than the total number of votes cast in the entire Republican Primary in Jefferson County.
