State laws would have come in handy when the previous administration was flying illegals in and dropping them off all over the country.
I came across an article that gives me a good guess as to why this was probably being done.
While America's heart of compassion was being manipulated with bleeding heart stories as supposed good reasons through the media propaganda, I believe the real reason this was being foisted on America had to do with in essence creating an unethical (and probably unconstitutional) means to gain electoral college votes for the Democratic Party. So, what's happened is representation of U.S. Citizens has been undermined greatly, in several states and with presidential elections.
Through the census, which counted illegals, this suddenly gave Democrats more representation power seats locally, state and congressional. These same districts are often devoid of any actual U.S. citizens (think California). This cemented Democratic power. Instead, we've got a situation that's for the foreigners and by a power hungry 'leadership'. As I see it, immigration, the generosity of the American heart and civil rights were weaponized towards this end.
I'm guessing illegals were strategically flown into parts of America where the Democratic party wanted to try and flip representation to their advantage via census counting. This is why they are desperate with a capital D, to fight the removal of such a lucrative situation through the deportation of illegals that's now being enacted. Their power source is slipping away and....desperate people do desperate things.
I'm also guessing that there are many voting Democrats who really haven't picked up on this, they've been distracted by the bleeding heart stories that came about in the first place from the major open borders. I hear this from good people in my life all the time. The bleeding heart stories are kept in the forefront of their attention (look here, not here), it's a sleight of hand:
Without Illegals, Republicans would control the country.

...Subtract even the most liberal number of illegal aliens and California would lose 4 seats (in addition to the one it already lost) bringing its congressional delegation down to 48 seats. That would be bad news for efforts by the Democrats to retake the House, but it would also cut California’s power in the electoral college and would make it harder for the Dems to win presidential elections. That is why they’re willing to risk civil war for illegals....
...If America’s illegals were to be deported, Democrats could lose as many as 15 electoral college votes and close elections would naturally trend toward Republicans. The political map would change. Democrats would cease to be competitive in national elections without fundamentally reorienting their message...

ing for our leaders on many fronts, and our country.
