The state suspended in-person caucusing, originally scheduled for April 4, and moved to a vote by mail system because of the coronavirus pandemic. In the 2016 general election, Donald Trump won the state with 68.17% of the vote, compared with Hillary Clinton’s 21.88%. Wyoming, a GOP stronghold, has voted for the Democratic presidential candidate only once since 1948 (Lyndon Johnson in 1964). The GOP controls both of Wyoming’s US Senate seats, its lone US House seat, both chambers of the state Legislature and its governor’s office. With a population of roughly half a million, Wyoming has fewer residents than all 49 other states and the District of Columbia.
