Here, but that's just for starters:
Hentoff called this the worst state the country has ever been in, “Even worse than Woodrow Wilson’s regime, when people could be arrested for speaking German.” Compounding the problem he says, is the digital age, which has allowed the president to engage in unprecedented domestic spying with the apparatus of the National Security Agency. WND asked if Obama really posed such a threat, considering he was a professor of constitutional law. “People forget, he taught a course that he was not fully qualified to teach. But nobody seemed to care,” Hentoff observed.
He also pointed out that Obama was the only editor of the Harvard Law Review to never publish an article, something that went virtually unnoticed when voters considered his qualifications. “See, that was a case of affirmative-action and people feeling, ‘Hey we ought to do something important, symbolically, and here’s a black guy, and he’s articulate, so we’re gonna do this.’”
Hentoff mentioned that former U.S. Supreme Court Justice William O. Douglas, the man Time Magazine once called “the most doctrinaire and committed civil libertarian ever to sit on the court,” once personally lectured him that “Affirmative-action on a racial basis is a total violation of the 14th Amendment, no doubt about it.” And, referring to Obama’s presidency, the journalist said, “That’s what that kind of affirmative-action did for us.”
He told WND that he firmly believed the president does not care about due process, the separation of powers, the concept of a self-governing republic or many other basic American ideals. And that’s why, he said, “What Obama is doing now is about as un-American as you can get.” Hentoff wanted to make sure no one thought he was engaging in hyperbole. He said it was literally true that Obama is “the most un-American president we’ve ever had.” And just to make sure everybody heard him, he added, “I hope the FBI got all of that.”
