Additionally, you appear to be conflating election fraud with apportionment, and those are two different components that the Democrat Party has used illegal immigration to swing each of them in their favor.
The first component is election fraud. And their efforts to bring this many people illegally in to assist in giving them victory in the 2022 mid-terms and the 2024 Presidential election is the end goal. You need to keep in mind that the number of illicit, manufactured votes to swing an election is vanishingly small in comparison to the total number of votes. I have heard it is in the range of a few hundred thousand votes or less. They simply need to be manufactured and strategically placed.
The second component is representation in Congress which is determined by the census. It is apparently a zero-sum game, that is, there is a set number of seats, 435, each state gets a minimum of one representative. This explanation from the Census site describes further how the apportionment is calculated:
I did not wish to soil my browser by going to that website, but in the interest of fairness I did, and one of the key points is the number of illegals in this country. The author goes with the lowest number of 11 million, but that is clearly a leftist number. I have always thought it was closer to 20 million, though some say it is a minimum of 25 million. Right off the bat, that 11 million number is absurdly low, not worth consideration.
