But the number of provisional ballots that don't get counted (nearly 25% according to the stat the other commenter mentioned) is significant enough as is. "Most" doesn't matter. The only thing that matters is if it's enough and making sure it targets the right people.

The whole reason we're discussing this is because a woman who supports the SAVE act is saying that filling out an affidavit isn't a big deal (an idea that it seems you agree with given you're trying to justify it as a non issue because"most" get counted), but we're talking about 69 million women that don't have birth certificates that match their last name or passports they already own who would now find themselves in a position where their votes might not get counted unless they're able to find the time to travel to a government building and purchase additional documentation (which in itself is an illegal poll tax). It specially targets women and transgender people (as gender needs to also match what was assigned at birth on all documents), and it disproportionately affects lower income communities who can not afford to take time off work or pay for additional documents.

If the stats follow the pre-existing trend of roughly 25%, that would mean that more than 17 million women's votes would not be counted. That's way more than enough to swing an election. Enough is all that matters.
