Why do you think that "person X supports candidate Y" implies "candidate Y will help person X commit more crimes without penalty"? Is that true of all people and all candidates, or only some?
I don't like the word "supports" for providing services at a high level in the campaign, but yes, I do think that in general, politicians attack their enemies and protect their friends.
An admittedly cynical view I've developed after years of watching partisan prosecutions, impeachment votes, and pardons.
