Scalia wasn’t just being hypocritical. He was, quite blatantly, lying. If he actually believed what he claimed to believe in Windsor, then he never would have joined the decision to strike down the Voting Rights Act in Holder. To the contrary, he would have denounced John Roberts’ opinion with venomous glee. To absolutely no one’s surprise, he did not. Because everybody knows he was lying in his Windsor dissent. Everybody knows he’s been lying for decades.
The whole five part series is worth a read. The conservative movement is basically founded on this kind of BS.
