There's always the mid-terms. If Trump loses both houses of Congress (or even one), we might see the White House lift off it's foundation and go into orbit ~ metaphorically speaking, of course. It would be better if the Sulphur and brimstone that inhabits Trump's head just causes him to self-combust.
Add to that the political finality of the Muller investigation and perhaps even a frog march or two. That will be bigly ~ or ugly ~ or better yet, both.
Articles of impeachment are also a possibility. Pelosi, if Speaker, says "no" to impeachment. But then, politicians say the darnest things, don't they? (wink, wink)
Then there's the royal snub when Prince Harry get's married ~ while Obama and Michelle (personal friends of Harry) are invited as overnight guests of the Queen at Buckingham Palace. Oooo, OUCH! Trump will be scratching that scab for years.
