Before the anti-Trump movement became a trending hashtag, Wisconsin conservatives were among the first Republicans to raise red flags about the brash billionaire who would go on to win the party’s 2016 presidential nomination.

Members of the anti-Trump movement in Wisconsin trace its origin to Rep. Reid Ribble, R-Sherwood, declaring in early December he would not vote for Trump if he were the nominee. That was two months before the National Review devoted an entire issue to the case against Trump and #NeverTrump began trending on social media.

Wisconsin was the last state where Trump lost in the primaries on April 5. Wisconsin conservatives, especially the talk radio crowd, presented a unified front against Trump in the weeks before the primary, backing Texas Sen. Ted Cruz.

Trump further alienated himself from Wisconsin conservatives during his first campaign stop in Janesville, when he criticized Gov. Scott Walker, said the state had a lot of problems and suggested Republicans should have raised taxes to pay for roads and schools.

Larry Sabato, director of the University of Virginia Center for Politics, described that week in Wisconsin as the moment when Trump could have been stopped.
