It would be funny if the court decided that he could remove his name from the ballot but that the result would be his opponent was now running unopposed.
That would not only be funny, it would be impossible. Senator Pat Roberts, the Republican incumbent, is already opposed by an Independent candidate, Greg Orman who is ahead of Roberts in the polls, and a Libertarian candidate who is along for the free ice cream.
Orman is already on the ballot. There is no reason for the court to remove him.
