My guess is that his speech will be some version of, "I am in disagreement with much of the platform at this convention, and in normal times I would be at the RNC arguing against it, but in the end, we would all be on the same side: America's side. That is what democracy is all about. But these are not normal times. We are in an existential crisis, democracy is on the brink, and that being the case there is only one way I can vote: for democracy. And democracy is being upheld by only one candidate, which is why I will cast my vote for Kamala Harris for President of the United States."
