I think the current Trump plot is actually waaay better than the original. I actually thought the original Trump storyline from the-gulp-80s was one of the strip's weakest. If nothing else, it meant we didn't have Bill the Cat acting like, well, Bill the Cat.
That being said, I agree that I don't want the new strip to be all Trump, all the time. Give me some more Milo, some more Portney, more Oliver and, especially, more Steve Dallas.
