Sulla showed romans a pathway and example to exploit the system which future dictators would mirror. He shifted the Overton window just like Trump has, but there are a lot more obstacles one has to tackle in a modern age. Imagine if a few senators had several legions of soldiers and were military commanders, that just isn't possible today in modern times. Sulla had bands of thugs to intimidate voters etc. In a way Caesar followed his path but Caesar in many respects was actually a real populist, in his will he actually gifted every roman citizen like 500 denarii upon his death but senators were very afraid of his power. Then Augustus followed Caesar as the first Emperor, so the senate completely failed to stop dictatorial rule. Someone could certainly follow Trump's type of gameplan and if they're far more intelligent and capable it could be scary, but they definitely face way more roadblocks than Sulla, Caesar, Pompey, Augustus etc.
