As moderator of a site on higher education, I get to follow various "news and opinion" sites. I find that Dershowitz appears consistently on the right Wing sites. Calling himself a liberal is ludicrous. As with all of us [almost] he is made up of opinions about subjects. In his case, most of them seem to favor the "fa" side of the ledger.
A prime example of his thinking is his argument that 45 could not be convicted because, as president, if he does it for what he considers good and sufficient reasons, then his behavior is legal. Rather twisted, what?
