This is exactly what leftists told Liberals what would happen if they allowed someone like Biden to win the nomination in 2020.
If Democrats nominate Joe Biden, he may win, and we'll have four years of weak, feckless Democratic leadership. And then, in four years, he'll be defeated by a Republican Party even more openly white nationalist. If you nominate an Obama redux, you'll just get a worse Trump redux.
