“prosecution of the president...is a far easier way to remove him from office than impeachment.”
You cannot prosecute the president until he has been removed from office. The only (legal) means of removing him from office is impeachment. Your proposal is a nonstarter.
Obama has qualified immunity and de facto complete immunity until such time as the house chucks him out. The courts can allow him to be sued like Clinton with Paula Jones or order him to turn over tapes like Nixon. But it’s not as if Nixon could’ve been attested for obstruction of justice while he was president. In the first place all he’d have to do is plead guilty and pardon himself.
Read the whole article. It's not about impeachment. The relevant portions of the statute are detailed there. If Obama violates any portion of that law (which he probably will), he most certainly can be prosecuted and removed from office.
The only question is, who's going to have to cojones to do it? The author (Dr. Jack Wheeler) suggests that several red state Governors could band together and bring suit, as provided for in the law.
I'm going to send this to my Governor, Rick Perry, my House rep, Kenny Marchant (R-TX), and both of my Senators, one of which is Ted Cruz (R-TX).
