Yes, he should be investigated:

There have been weak presidents, deluded presidents, and harmful presidents before him, but never has there been anyone as sinister or questionable as Obama, not excluding even the malefic Jimmy Carter or the sleazy Bill Clinton. What J. R. Dunn writing in American Thinker has said of Hillary, “the most repellent and corrupt American presidential candidate since Aaron Burr,” is equally true, in my estimation, of Barack Obama. Meanwhile, it is Trump who faces a barrage of threats, calls for impeachment and acts of disobedience that would have been more explicable if levied against Obama for his historic deceptions and malfeasances. Under the pestilential reign of Obama, and indeed years of Democratic incumbency, the shining city on the hill has become a murky city in the swamp.

The trouble with Barry is not only that he refuses to go away, materializing like Harry where he has no business being, or that he enjoys, à la Hitchcock, making cameo appearances in whatever political film he happens to be directing at the moment. All this would be perfectly acceptable, even agreeable, were he a benign presence or if he had Hitchcock’s talent for deadpan humor and high entertainment rather than a penchant for malice and misconduct.

He seems determined to outdo Jimmy Carter as our worst former President.

They’re still withholding 7000 documents that show how (as Koskinen himself admitted) they were targeting conservatives.

As I wrote on an email list this morning (in the context of Big Data, Facebook and government spying): “I’m much more worried (or at least was in the last administration) about being targeted as a “right-wing” (i.e., someone who is a classical liberal, and gives a s**t about the Constitution) rather than Islamic terrorist, if they’re looking through my contacts and statements. And I think that the previous administration was the worst since Woodrow Wilson in terms of targeting what it perceived to be its political enemies (including through the campaign…). I’d call it Nixonian, except Nixon didn’t get away with it.”

Popehat shows how this works. As he says, Colorado doesn’t have an anti-SLAPP law, but it may just get dismissed.

By the way, while I don’t generally discuss my own case, briefly, because he’s a public figure, if it ever actually gets to trial, he has to show that I acted “with malice.” Legally, what this means is that I had a “reckless disregard for the truth,” which means that I either knew what I was writing wasn’t true, or I didn’t care whether or not it was.

Whatever else you might think of him, you know who recklessly disregards the truth every day? Donald J. Trump. Though Barack Obama did it a lot, too, to cram ObamaCare down our throats (among many other things).
