More less irrelevant. How many polling places is there, how many ICE agents do they have?
How could anyone even hope to affect the results by only interfering in >20% of voting locations? Obviously irrelevant.
Luckily it doesn't matter that even interfering at 1% of polling places is very likely enough to sway the US election, right?
2. You have to register to vote, so you have already proven that you are a citizen, thus the whole theater with ICE is double irrelevant.
