An example [0] suggesting ~0.0004% bad votes in an election is not a meaningful example unless you want to sneakily redefine "the problem" away from "significant numbers of bad-votes may change results" to a pointlessly bland "some nonzero number of bad-votes happen." [1]
If cases are as persistent and widespread as those politicians claim, it should be much easier to find similarly-large-scale evidence. (For example, their mythical "buses of illegals.")

That "example" is nonsense.
1. It has nothing to do with non-citizens (or felons) registering to vote or casting ballots. The thing Texas "can't investigate" is an entirely separate crime the state recently added to their books, involving a different set of people doing different things.
2. The reason they're being blocked from prosecution is because they passed a shitty law with a crime that might unconstitutionally restrict freedom of speech, not because the state doesn't manage and audit its own voter-rolls and election systems and enforce existing criminal statues.
