Although still one of the more Republican regions of the state, in the following years Democrats have made inroads and today it is an important swing county, correctly picking the winner of every presidential election since 1996. Both Republicans George H.W. Bush and George W. Bush would win it twice each, but Democrat Bill Clinton won it in 1996, and Barack Obama has won it twice in both 2008 and 2012, bolstering his wins of the state's electoral votes each time. In the 2012 presidential election, "Time" had listed Hillsborough as one of five critical counties affecting the outcome in the swing state of New Hampshire. Obama ended up winning with a margin of 50%-49%. Although Donald Trump narrowly won the county in 2016, the county swung hard to the left in 2020, giving Joe Biden 53% of the vote, the highest percentage for any Democrat since 1964.
