Waht caused Roberts to renege?

Thugbama Roberts changed vote at last minute ... Ahem “ Intelligence and security experts are outraged at the Clinton administration's probable use of blackmail and susceptibility to it as the Congress fails to investigate. The Clinton Team and Blackmail ” Now we learn that Roberts switched his vote!  I'm thinking the same thing most of you are.  Going forward from the commencement of Obamacare hearings,,  there were frequent- if not daily- stories about threats (pressure) being put on the court by Obamunists.  Rewind to Clinton's impeachment trial in the House.  It is widely believed that Hillary gave her purloined raw FBI files on congressional Republicans  to pornographer Larry Flynt,  who used them to blackmail Republican House members, and most likely Senators (who failed to convict him).  We know that at least three House Republicans, Livingstone, Hyde and Barr refused to submit,  and had past marital infidelities  exposed. Don't think for a minute that this thug  administration would  not use the same tactics, as I believe they did.   Roberts was found wanting.  And there was this, from just a few weeks ago (June 21). I am surprised by the 7-2 decision:  I woulda guessed 5-4.  There have been a few more recent rulings the same way,where I was surprised over the libtard vote.  I can't help but worry that there is a quid pro quo at work here — by the liberal justices to gain the deciding vote in Obamacare (which looks like Monday). I know, silly. After posting, I felt stupid because I know that justices vote immediately after the oral arguments are finished, so, I thought, what a stupid thing to say. My stupidity had to do with not realizing a justice could change at the last minute.
