Routt County tilted Republican for much of the second half of the 20th century. From 1952 to 1988, Republicans carried the county in all but one election. The one break in this trend came in 1964, when Lyndon Johnson won Routt by a healthy margin of 63–37. Since the late 1980s, Routt County has trended Democratic. It swung from a 34-point win for Ronald Reagan in 1984 to only a five-point win for George H. W. Bush in 1988. In 1992, Bill Clinton became the first Democrat to win the county since 1964 and only the second since 1948, carrying it with modest pluralities in both of his bids. George W. Bush won the county in 2000 by only 64 votes. However, John Kerry won it by a 10-point majority in 2004, and since then Routt has become powerfully Democratic, with Democrats winning by margins rivaling those in the counties closer to Denver. In 2016, Hillary Clinton won the county 54–37. Routt County continued its Democratic trend in 2020, with Joe Biden winning the county 63–35. This is the largest margin of victory for a Democratic presidential candidate in the county since the 1916 election.
