Many people seem to have a favorable opinion of him, for supposedly defending the Roman republic during its collapse, but seeing his history and actions he did everything to defend the interests of the Roman elite to the detriment of the Roman population, and abused the system against their enemies when it was convenient and was a landowner famous for building the buildings in a horrible shape. Still, it has a reputation for having defenders to this day.
I was listening to people reviewing the first season of HBO's Rome, and what stuck with me is they pointed out that post-2016, the Pompey/Anti-Caesar faction seems like the most out of touch geriatric Democrats. Even if they are in the abstract on the right side, they are so dedicated to the status quo and can't seem to understand that things have moved on, and people don't believe in the forms or institutions anymore. So they are stuck defending institutions from the right and complaining about how Trump/Caesar is not following the norms.
