There are surface similarities but more than a few differences. Off the top of my head.
DSP is lazy, thats one of his primary characteristics. I don't see how you can call Trump lazy. Even if you think he's entirely self interested and golfs a lot he does more shit in a month even before being president than most people do in their lives.
DSP is cowardly and hides in his khando. Trump doesn't, or at least nowhere near as much.
DSP is victimized by casinos, Trump runs them.
DSP flipflops from second to second and has no coherent ideology. Trump at least since the Presidency has maintained a somewhat consistent worldview.
Unlike his rivals who largely have spent their entire lives in safe government jobs Trump has spent most of his life in the private sector. True he's gotten a headstart, like most of his rivals. And he's failed multiple times. But he's always gotten back up and better than ever. Even most people with private sector success simply succeed once and then safely ride it out. Now you might say DSP has gotten back up several times too but actually DSP has no job and begs for a living.
Its largely agreed that both DSP and Trump's IRL personality are considerably different from their media personality. DSP is largely considered weird and standoffish. Trump while considered by some to be a harsh taskmaster in professional settings is largely agreed to be affable in personal settings. (I don't know him personally to confirm, this is just whats available online so take it as you will)

Trump has a hot wife and an actual family. DSP has a cat
Trump is at least a personal success by any reasonable definition.
The side opposing Trump is arguably far crazier and more dangerous. I'd call it about even between tractors and dsppaypigs.
