For much of this, Mr. Ryan has only himself to blame. Not only has he made several errors during his speakership, he's being criticized for running an overly centralized House, just like Jim Wright and Newt Gingrich. Meanwhile, his wonky reputation with the media has suffered mightily as his bills on health care and taxes landed with few signs of political or policy mastery. Just as was the case with his old mentor Jack Kemp, Mr. Ryan's skills remain those of an ideological propagandist, not a legislator or a congressional tactician. There's a place for those strengths in Congress, but it's not a great fit for the speaker's chair. Perhaps he won't be there much longer.
