Once Biden vetoes this (which he and his people say will 100% happen) Trump and Republicans running for H and S nationally should make this their #1 talking point from now to election day, along with the question "why?????"
The Democrats argument against this bill is that it is already illegal for non-citizens to vote. But, there are no protections to prevent non-citizens from voting, especially in blue states. In fact, some states have made it illegal to ask if an individual is a legal citizen or not. In any case, it is the stupidest argument from Democrats yet. It is also illegal to rob banks, but banks still keep their cash in a vault. Imagine if we used the honor system for everything? Banks can't lock up money because it is already illegal to steal. Car have no locks and no keys because car theft is illegal? We've already seen what happens with situations like this. Mobs of hoodlums storm retail stores and clear the shelves of merchandise without paying! Now those store have resorting to locking everything behind glass partitions or they shut down completely.
And why don't Democrats apply the same logic to guns? Murder is illegal, but that doesn't stop them from wanting to control guns.
The is only one reason to oppose the SAVE Act and that is to allow cheating.
