The Gingrich marriage  highlights the sheer hypocrisy in the RCC.  It was Wuerl himself who received Newt into the Catholic church, after he had obtained (one or two) annulments.  He had affairs with wives 2 and 3 for years before divorcing and remarriage.  The conservative Catholics who are angry with Francis about his ideas on divorce and remarried people being eligible for communion are simply fine with serial marriages by adulterers as long as they toe the line and get annulments, as many as needed.  

This seems a way of pacifying Newt, who seemed to expect a big job under Trump,  after not offered the VP slot.  Trump can use Newt's wife to fill a job that he thinks totally unimportant, and maybe even get Newt out of town.  Callista will  wine and dine in Rome and effectively do nothing.  Flipping birds at Newt and Francis at the same time.

I wish it had been Bannon. Bannon is a danger to our republic. Getting him out of town would be a service to the nation. Callista - harmless.
