Buying Their Votes With Your Money

Very quietly (of course), the junior Senator from New York has proposed a bill (SB 419?) to grant a tax "refund" to Puerto Ricans. Just one problem: Puerto Ricans pay no income tax. This raises a couple of very interesting questions:

1) How do you "refund" money that was never paid in the first place?

2) Why have the dominant media not called her on this?

3) Will the Puerto Rican voters of New York be stupid enough to vote to re-elect her to the Senate next year?
