Study Reveals the Lasting Voter Suppression Effects of Restrictive Texas Law

S.B. 1 had a UI problem that I'm surprised the legislators didn't notice (or ignored):

> S.B. 1 required voters to provide their partial Social Security number or state identification number (essentially a state SSN) on mail ballot applications and again on mail ballots. The number they provided had to match the number used when they registered to vote. In other words, if a voter registered using only their Social Security number but later provided their state ID number on their mail ballot, their ballot would be rejected — even if their state ID number was valid.

But take the causal claims in the article with a grain of salt.
