Your TDS and historical ignorance is showing, fren. Andrew Johnson was hated by everyone, including his own party. Trump is extremely divisive (I mean, he got you to vote for a war-mongering corporatist after all), but he is extremely popular with a lot of people. He gained more support from minorities than any republican in sixty years, after all.
This is also a reason the fraud pisses me off. The Democrats have fucked us over with Republicans, because they are now going to think it's poison to try and reach out to minorities, when it isn't. There's a stark difference between normal folk who happen to be darker, and hood rats, rez rats, etc.
