Unlike the Vatican, of course, the United States allows millions of people into the country legally each year. Good luck trying to stay over night in the Vatican.
But the Italian Pope who served in Argentina's venture into American politics is a colossal blunder because it shows the gulf between American Catholics and Pope Francis.
The Reuters tracking poll shows:
Donald Trump 33.2%But among Catholics only, the numbers are:
Wouldn’t vote 26.5%
Ted Cruz 11.3%
Ben Carson 9.4%
Marco Rubio 6.8%
Donald Trump 40.0%Neither John Kasich nor Jeb Bush cracked the top 5 in either poll result.
Wouldn’t vote 24.0%
Ted Cruz 11.0%
Marco Rubio 9.6%
Ben Carson 5.3%
In summary, four times as many Catholics prefer Trump over the sole Catholic in the Republican race (indeed, in the entire race). That Rubio was quick to disassociate himself from the Pope's trashing of Trump shows an understanding of the flock that the Pope lacks.
While the Pope is more popular than Trump in the United States, the Pope is not on the ballot.
