They are allowed to vote, but what I see is some folks questioning why they should. It is not a nefarious action to register to vote. Speculating as to why they might be registering to vote as some egregious act is silly. They have every right and they now have every reason.
“They have every right and they now have every reason.”
Simple self defense has been one answer.
But, as a citizen, I can look at history and see that their past practices include dominating the voter rolls, putting in their own leaders, and and continuing to violate the law.
I can then speculate that it might be another option, rather than some ‘sudden light of patriotism’ that occurred to them all at once.
If you live in that county, you can at least do something, if you think they are trying to ‘takeover’ the political system, like go vote yourself.
