This article is in desperate need of citations and a public revelation of the calculations involved. It also has problems. I can't speak to other states but where it does mention Pennsylvania, where I live, it omits critical information.
In Pennsylvania (19 electoral votes), the Poison Postcards wiped out 360,132 voters, three times Trump’s victory margin.
These don't get sent out for fun. This is how the ordinary voter roll maintenance works. The cards are sent out after you fail to vote two consecutive federal elections, or when the department of state gets notified you moved or died through some other means, not for 'targeting' voters. You only actually get purged from the roll if you fail to respond to the card AND fail to vote for at least five consecutive years (This isn't specified as far as I know, but a product of the timings involved). If you show up and vote in every presidential election, you do not get removed from the rolls even if you throw out the postcard. So if this:
According to the EAC data, before the 2024 election, 4,776,706 registrants were removed nationwide simply because they failed to return the postcard.
Includes Pennsylvania, it is simply false. You can read the actual law yourself, they are all online. It's PA Title 25. Chapter 19 lays out the rules for removal.
Details on Pennsylvania specific mail-in ballots being cancelled, which is a real issue, are woefully absent. According to the Governor's office only about 1% of the 2 million returned (about 20,000) mail in ballots were rejected.
Of the roughly 1% of mail ballots rejected in the 2024 general election, the most common reasons for rejection were:
receipt after the 8 p.m. deadline on Election Day (33%), incorrect or missing date (23%), lack of a signature (17%), and lack of a secrecy envelope (15%).
Harris lost by ~120,000 ish votes in PA. 'Clerical errors' are not even close to closing that gap.
It also mentions Secretaries of State being partisan hacks, but some odd reason fails to mention Pennsylvania's Secretary of State was appointed by our Democratic governor who was not only a Democrat, obviously, but short listed for consideration as a running mate for Harris. Nevertheless, it is implied we should concerned about his Secretary of State targeting voters from her own party for removal in an election that could have had handed the governor his own path to the White House. Forgive me for my skepticism.
Voter suppression is a big deal, I'm sure there are elections it will swing at times. Heck, there is a fair chance it swung the senate race in PA since that one was only decided by ~15,000 votes, but based on what I already know, this article isn't credible enough to be taken seriously in its current state.
