He and the GOP will more than make up for any donor losses with the pick up of hispanic votes. He's already shown the trend is in our favor with his results in the past election. He just needs to deliver.
Legal hispanics dislike the idea of an amnesty for illegals as much as any other legal residents or citizens of the US.
In any event, this amnesty will not solve the illegal problem. If you make all of the current illegals legal, that just opens up room for even MORE illegals who can be paid lower wages and treated like dirt by their employers.
The employers who hire illegals have no desire to see those illegals obtain some sort of legal status.
