President Obama has been a flagrant abuser of his office. He has used executive orders and other mechanisms that have been found to be in violation of the law and the Constitution. As a result, his Justice Department comes in dead last when it comes to the win column in the Supreme Court:
As a serial abuser of the law and the Constitution, I think Obama has forfeited his right to appoint Justice Scalia's replacement. For sure, he will try to appoint someone that he thinks would have best served his own recklessness; and that, in itself, would be an injustice to this country.
