No, not a joke. A plain insult to Trump, nothing more. (and yes, I know you're "trying" to make a joke yourself...)
It's not that it's an insult to Trump. Nobody cares about that! It's the lack of an actual point that makes me think the meme is worthless and stupid.
Besides, I'd put money on Trump in a race against Biden, Warren, or Sanders (or all three at once.) No golf carts allowed!
