In a live-streamed debate on May 22, 2020, in a ballroom devoid of spectators due to the COVID-19 pandemic, all five major candidates praised president Donald Trump. Kobach took on his opponents who all agreed that he could not win the general election against presumptive Democratic nominee, Bollier. Marshall said, "We cannot afford to send a failed candidate back this fall who will lose to Barbara Bollier and hand the Senate majority over to Chuck Schumer." "Instead, we need to send a tried and trusted friend of President Trump." Referring to Marshall, Kobach replied, "Do you want a go-along-to-get-along kind of senator, a gutless wonder who never takes a stand, or, do you want someone who poses a threat?" Hamilton said voters didn't have to choose between Kobach, who couldn't win, and a moderate Marshall, in whose behest the state party leaders had urged Senator Wagle and Lindstrom, to drop out of the race. Objecting to the party pressure, Lindstrom characterized his opponents as "shortsighted, self-serving...career politicians who are divisive, controversial," and, "have a record of losing elections." Wagle touted her own candidacy, saying, "It’s very, very important that we send a leader to the U.S. Senate who is articulate, who is persuasive, who other people respect." "I'm the one who's already debated Barbara Bollier." "I win on the Senate floor. I've beat her numerous times," "...the conservative voice that can beat that liberal voice in the U.S. Senate," she said. In response to a claim that he would not prioritize the issue of agriculture, Marshall said, "Fake news and another lie by Kris Kobach."
