There is only one issue in the world, now and for the foreseeable future. It's multifaceted and we have to solve a number of other problems to solve it, including the emptiness and addiction that put so much money in politics (and cause so many other problems) and the splitting, projection, and objectification involved in racism (and in so many other problems.)
As long as we have the political-economic structure we have we're unlikely to avoid climate cataclysm and the resulting deaths of hundreds of millions at least, and the extinction of millions of species at least. One symptom of that structure is that neither of the current corporate duopoly candidates for president will ever do what's needed to avoid the approaching catastrophe without being forced to. No other issue is threatening to cause the end of civilization within the span of people now alive, so the upcoming election is a serious problem, too, and saying one person is worse than the other neither solves the problem nor avoids the inevitable choice between revolution and destruction.
