The democrats don’t really care about illegals. They care about losing power...
In four short years there will be another census. Certain states will need every illegal counted in order to not lose a representative in Congress. It’s a double whammy for states like New York and Illinois. Not only will they lose another pig at the D.C. trough, they lose another guaranteed electoral vote for the ‘rats.
After the 2010 census, we should experience a net gain of 4+ electoral votes.
This will have the same effect as the democrats losing a reliably small blue state like Maine.
