Poll taxes were used to keep southern blacks from their right to vote and were banned by the 24th Amendment:
If one does not have insurance and does not pay the 2.5% tax mandated by HR3590, they would be guilty of a felony and go to jail, thus losing their voting privileges. Thus the effect of the 2.5% penalty tax is indeed a poll tax. Add this to our list of ways the bill is unconstitutional.
Section 1. The right of citizens of the United States to vote in any primary or other election for President or Vice President, for electors for President or Vice President, or for Senator or Representative in Congress, shall not be denied or abridged by the United States or any State by reason of failure to pay any poll tax or other tax.
Section 2. The Congress shall have power to enforce this article by appropriate legislation.
