Donuel, this is a difficult task, especially as it's you, but allow me to apprise you of how to get at least a faint titter out of political jokes. Try these two:

"The word politics comes from 'poly', meaning 'many', and 'ticks', meaning 'bloodsucking parasites.'"

Geddit? Did I detect a faint titter?

If that didn't work, try this Ronnie Raygun one, allegedly a genuine quote:

"I have left orders to be awakened at any time in case of national emergency, even if I'm in a Cabinet meeting..."

See what the rules are? Simple! No twisted, bitter cynicism. An attempt at humour. If you make it up yourself (incredibly ill-advised in your case), try it out on a critical but sympathetic friend (if you have one) before trying it out in public. And one last thing you've yet to absorb: you cannot have a joke about Donald Trump. Go on, give it a whirl!
