Wolfe should hold a debate...announce he’ll take all questions..including from the audience..have a moderator, and three newspeople to ask him questions..and have an empty chair, or a life size cutout of Roberts on the stage..
Wolfe should challenge the Demonrat candidates to debate. Just treat Roberts like he already lost the nomination and move on to the Nov election debates.
The Dems will likely refuse, and at that point Wolfe can run as the candidate they ALL are afraid to debate.
Either way it would get him in the news, and give him lots of free advertising on TV.
