Voter registration gets names cross referenced to facebook gets you face recognition (Palantir can do this). Ice claims that facial recognition on their app is probable cause (Ice already claim this).

Ice goes down the lines at voting stations to "protect from undocumented aliens voting illegally". The government endorsed news stories will be about how many illegals were trying to vote. Meanwhile a bunch of US citizens were taken for processing due to false positives and unfortunately with such large numbers to process they aren't all released until polling stations are closed. (If only someone hadn't botched the facial recognition database update and contaminated it with a bunch of Dem voters).

If rioting against these actions occurs at a station, it's closed for safety and people in area are detained while it's sorted (the stations targeted had a tendency to vote D anyway as per voter roles).

Strange how that 'harassment' did stop US citizens from voting.

Results come in while the case for voter suppression goes to the Supreme court. Supreme court rules that while voter suppression did occur there is no legal option of redress within its permit and the peaceful transfer of power is more important than any one election A la Bush V Gore.

Nonetheless, it was successfully implemented for about 100 years in the US.

Seeing as the harassment has escalated to murder of citizens, I'm not so sure how you can say that.

Less sensationally, they'll just crank up ID requirements and wait times to suppress your vote.

Are you a citizen, can you prove it at the polling station? I am doubtful you are, and your documents if you have them don't seem legit enough, so I think we'll set your vote aside, or possibly prevent it from being cast; we can't be too sure!

you should read up on efforts to suppress the vote of certain US citizens, especially those who are poor and/or of color
