The true left should defend democracy, but what Democrats defend is positive discrimination, censorship of incorrect thinking, and submission to their agenda and global elites.
This is the total opposite of democracy, which is why they should not receive a single vote, as they are corrupting their political role.
And this is why much of the leadership of the current Republican administration was formerly Democratic, including Trump himself. They were forced to take refuge on the right, which defends freedom, to avoid the dictatorship of the false left.
