The Never Trump movement, also called the #nevertrump, Stop Trump, anti-Trump, or Dump Trump movement, began as an effort on the part of a group of Republicans and other prominent conservatives (known as Never Trump Republicans) to prevent Republican front-runner Donald Trump from obtaining the Republican Party presidential nomination and following his nomination the presidency for the 2016 United States presidential election. Trump remained unsupported by 20 percent of Republican members of Congress in the general election. Following Trump's election in November 2016, some in the movement refocused their efforts on defeating Trump in 2020.
