Is this guy the worst solicitor general ever?

The Solicitor General is basically the President's top appellate attorney.  He or she argue important matters of federal law in front of the Supreme Court of the United States.  The office was first established in 1870.  Among our past Solicitors General are the likes of William H. Taft, Archibald Cox, Thurgood Marshall, Robert Bork and Ken Starr.  Impressive barristers one and all.  Obama chose one Mr. Donald Verrelli, Jr. to be his principal advocate before the Court.  And I am not sure if this guy can even string a sentence together let alone parse through a cogent argument at law.  You may remember that he was universally slammed for stammering his way through the oral argument over Obamacare.  Don't get me wrong, he was dealt a bad legal hand.  Nonetheless, there were arguments he could have and should have made.  He just could not seem to get any of them out.  Well, my brother at the bar Mr. Verrelli is once again showcasing his advocacy skills, this time in arguing to overturn the Arizona immigration law.  And once again he fumbled and stumbled.
