It's way early but this is an interesting opinion from a liberal (oh horrors !) columnist.

Don’t quote me on this, but I think Jesus also took a hit in his poll numbers when he kicked the money changers out of the Temple, broke bread with prostitutes and reminded the religious elite that their obsession with the letter of the law missed the big picture. I doubt a pope who is focused on bringing those on the peripheries to the center of global debates is losing sleep over the finer points of Washington punditry or polling. This is a pope who still remains enormously popular and is arguably the most compelling moral leader in the world today. Coveting thy fellow leaders’ polling numbers is likely a sin, but most politicians would do anything to have the pope’s widespread appeal.
