Meddling in politics?

More than two years ago, the Italian newspaper La Stampa reported on a talk Pope Francis gave about politics. According to the paper:

The Pope pointed out that there is a tendency to only speak ill of leaders, and to mutter about "things that don’t go well." "You listen to the television and they’re beating [them] up, beating [them] up; you read the papers and their beating [them] up. . . ." He continued, "Yes, maybe the leader is a sinner, as David was, but I have to work with my opinions, with my words, even with my corrections" because we all have to participate for the common good. It is not true that Catholics should not meddle in politics: "‘A good Catholic doesn’t meddle in politics.’ That’s not true. That is not a good path. A good Catholic meddles in politics, offering the best of himself, so that those who govern can govern. But what is the best that we can offer to those who govern?".
