One week from today, Pope Francis will mark the anniversary of his election.
A survey out Thursday of American Catholics finds that he is enormously popular. Sixty-eight percent say that he represents a change for the better.

Even so, the pope is not having the impact that you might expect.
Francis has more than 3.5 million Twitter followers, and in true celebrity fashion a fan magazine that monitors his every move.
But the new poll shows the pope's influence may be limited.
The number of Americans who identify themselves as Catholic is unchanged from a year ago, 22 percent. And of those Catholics, 40 percent say they attend Mass once a week, also the same as last year.
The Rev. Jim Martin is editor-at-large of the Catholic magazine, America.
"I think things may lag," he said. "I mean he's been pope for a year and I think people's faith lives - if you've been away from the church for 30 or 40 years, it might take more than a year to come back."
The survey did find that about a quarter of Catholics say their faith has deepened in the last year. Brian Stevens is one of them.
"I heard Pope Francis and his message and I couldn't stay away," Stevens said.
Stevens stopped attending church regularly more than six years ago. He said Francis' tone was welcoming.
"He's made me feel like there's a place for me in the church," Stevens said. "He's made me feel like I'm wanted in the church and not only wanted but needed to help bring about a better world."
But just 54 percent of U.S. Catholics approve of how Francis has handled the clergy sex abuse crisis.
