It is stupid, unless your intent is to insult the Vatican. Then it starts to make sense. Does this administration view the Catholic church as an enemy?
In the days of the cold war I don't recall the US and USSR insulting each other with radical ambassadors.
0bama's choices as ambassador to the Vatican have been either stupid on his part or meant to be insulting.
The Holy See has drawn a line in the sand, Barry can do it by the rules or do without.
Even without an ambassador to the Vatican 55%+ of catholics will vote for a democrat for president no matter how dastardly his/her policies.
At war with the church perhaps. Individually catholic voters are solidly in his army.
