I mean, trump seems obvious. Unstable wannabe tyrant/dictator from a party of evangelical theocrats, criminal, fraudster, blatant liar, thief, rapist, sycophant of dictators, insurrectionist, wife beater...and we haven't even dug in to the party that supports this behavior along with their LGBTQ hate, restricting womens' rights, voter fraud, election fraud, gun rights > your life, handing everything to the billionaires, environmental destruction of most every kind, and of course their NAZI underpinnings.
