So for you Harris is going to win with the votes of the inmigrants?
I have no idea who is going to "win" in either sense:
1.) Get the most number of legitimate ballots, since there is no election integrity the number of illegitimate ballots cannot be quantified therefore the number of legitimate ballots is also unconstrained.
2.) Get inaugurated as congress officially recognizes one candidate as the winner, since there are many factors that affect this including the number of fraudulent votes vs the number of people waking up to the lies of the deep state (and there are many, never before have two former democrat candidates for the presidency joined the republican nominee).
I do not believe in any case that a large number of illegal immigrants or legal immigrants are voting. Legal immigrants tend to follow the law and know they aren't allowed. Illegal immigrants are focused on a hundred other things and would only do it if they were paid, and the smarter ones would be worried about the attempt being a trigger condition for getting deported first.
I do think that illegal immigrants are registered to vote and kept on voter rolls so that the voter rolls have a large padding of people who won't attempt to vote. People on the registry who won't attempt to vote are precisely the pool of people, or rather names, that are used for mail fraud.
In other words cheaters pretending to be immigrants, illegal immigrants, or real (but not political) citizens would be sending in ballots in their name, and that is much more significant than illegals trying to vote directly.
A reminder: Once the mail ballot is separated from the envelope there is no way to repair the damage. The cheaters know they only need to resist the law until then because after that happens all the judges are too cowardly to invalidate the whole ballot pile no matter how egregious a vulnerability for cheating was created.
