Buying a future voting block on the backs of taxpayers who pay tax's with the expectation the government will use the money in ways that benefit the very people who pay those taxes.
Sneaky! But very effective!
only a future voting block in Federal elections if they become citizens - personally I think it has more to do with tilting the census to get more democrat congressional districts - - its why they so loudly tell everyone to return a census - no legal status required
