Today’s GOP insanity

[SilverFang01]

That is not a poll tax, a poll tax is a requirement for you to pay a fee just to be able to vote. Here what you have is someone having to finish the monetary part of their sentence. You see, when you are convicted of a crime there are court costs and restitution that are part of the sentence that you are required to pay. All this law does is make it clear where it wasn't before, that you are also required to pay these fines as well as having served your time.
From the first article

The new law requires people with serious criminal histories to fully pay back fines and fees to the courts before they become eligible to vote.

Voting rights advocates say that requiring a person to pay all of their fines and fees before registering will deny voting rights to hundreds of thousands of Floridians with felony convictions — a group civil rights organizations are calling “returning citizens.” Estimates have suggested that more than half a million people will be affected by the new financial obligation-paying requirement, and many will need to wait years to finish payments before they can vote. Others may never be able to clear their debts, meaning that they will be permanently disenfranchised.

Bolding mine. It quacks like a duck, etc.

The United States penal system already imposes penalties way beyond what could be claimed as justified, no matter the crime. The GOP is just using that feature to continue denying the right to vote once they lost the referendum. This in the end is no different from their shenanigans in Ohio Oregon because the end result is the same: denying a voice to the people they believe should not have a voice.

The GOP is making use of the Vetinary Principle: One man. One vote. The GOP is the only man. They have the only vote.
