Cutting off benefits and getting rid of anchor babies will not happen. The socialists won the Presidency. They won the Senate. That have nearly half of the House. They are 4 of 9 Supreme Court justices. Most of our OWN side are NOT conservatives. A good number of them are liberal rinos.
Your solution would work in a conservative world, but It is not going to happen. It is only in a dream that any such thing will break a conservative direction inside of the next few decades.
To make that happen we would have to own the presidency, a filibuster-proof Senate, and the House. And we would have to have all of our side be conservatives instead of “republicans”.
A Brotha’ can dream, can’t he?
