They aren’t winning, they just aren’t losing as bad as they could be.
All those illegals are not being deported and at the very least any kids they have will be American citizens.
More importantly, we aren't doing like we are "supposed to" and like the GOP usually does: fight for a while, lose and then get quiet about it and accept the change as the new status quo to retreat from again. We were supposed to complain for a while, then accept it and find something else to fight over, like was done with the 1986 amnesty.
Have the illegals stopped? Are we deporting the ones here? I doubt it. We have won nothing.
