@TonyStark How did today's "Republicans" accomplish these "supermajorities"?
Everyone needs to be aware that it were true Republicans, who introduced & passed the Fifteenth Amendment, the 1st of 3 Reconstruction Amendments, & that it's today's so-called "Republicans", who are constantly & intentionally violating it, to sabotage the will of the majority of American voters.
What does the 15th Amendment mandate?
"Section 1. The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude."
