While most of Utah is deeply Republican, Grand County has become a swing county in recent years due to many environmentalists and back-to-the-land types moving into the county. Although Bill Clinton won Grand County in 1992, the county voted for Bob Dole in 1996. In 2000 and 2004, Grand County voted for George W. Bush while supporting the Democratic gubernatorial candidates. In 2008, it was one of three counties in Utah that backed Barack Obama over John McCain. Donald Trump proved victorious in the county but by only 15 votes over Hillary Clinton.
Grand County was an epicenter of the Sagebrush Rebellion which took place during the late 1970s and early 1980s, when local residents protested what they saw as overreaching Federal control of Western US land.
One of the first major events in the Rebellion occurred on July 4, 1980. A group of 300 Grand County residents gathered behind a flag-decorated bulldozer, in protest of the inclusion of Mill Creek Canyon as part of a Bureau of Land Management wilderness study area. Despite plowing nearly 200 yards up the canyon, the group never reached the boundary of the study area.
The Denver Museum of Natural History opened a small Cedar Mountain Formation quarry that has produced diverse dinosaur fossils including theropods and ornithopods of varying states of growth.  An adult and juvenile sauropod were also recovered from the quarry.  The adult was designated the type specimen of the genus Venenosaurus.
