Johnson: The day the GOP died

Marc Johnson of The Johnson Post considers Feb. 18 as the day that the GOP in this country died:

If you are one who remembers important dates in history you might etch February 18, 2016 into your memory – as good a day as any to mourn the demise of the party of Lincoln and Teddy Roosevelt and Reagan. On February 18 two things happened – seemingly unrelated, but really not – that could well define an otherwise indefinable political season: Donald Trump got into it with the Pope and was shown (again) to be lying. Each event should have been enough to halt the arc of the demagogue, but it didn’t happen and it won’t unless serious Republicans start taking this guy seriously . Did any of us ever in our wildest, craziest political dreams expect the leading Republican candidate for president of the United States to shout down the Pope? More here.

Question: Did Trump go too far by criticizing the Pope?
