Barbara Boxer maneuvers to have more illegals included in 2010 census

I’m missing something obvious here, I’m sure, but doesn’t this mainly benefit reddish southern states?

U.S. states with large numbers of undocumented immigrants could receive additional seats in Congress after the 2010 census is conducted.

A University of Connecticut study concluded Arizona, Texas and Florida could all see their House delegations increase due to rising populations that include sizable numbers of illegal immigrants…

The Connecticut study also predicted California and New Jersey would likely keep their current number of seats while states with fewer immigrants, including New York, Illinois and Ohio, will lose a seat or two.

It seems like this is less some nefarious plan to move House seats nationwide from the red to the blue column than a bid by Boxer to leverage the huge population of illegals in her home state to protect its own House representation at the expense of other Democratic population centers. Exit question: What am I missing?

Update: Super-devious Kausian hypothetical: Boxer wants the representation of reddish states with huge illegal populations increased in 2010 in anticipation of a mass amnesty in the second half of Hillary’s term that will turn those states deep purple after illegals suddenly gain the right to vote! Genius.

Update: What about population outflow?
