Peggy Noonan‘s latest column for The Wall Street Journal focuses on an interesting turn in presidential popularity.

Barack Obama was elected president in 2008 because he was not George W. Bush. In fact, he was elected because he was the farthest thing possible from Mr. Bush. On some level he knew this, which is why every time he got in trouble he’d say Bush’s name. It’s all his fault, you have no idea the mess I inherited. As long as Mr. Bush’s memory was hovering like Boo Radley in the shadows, Mr. Obama would be OK.

This week something changed. George W. Bush is back, for the unveiling of his presidential library. His numbers are dramatically up. You know why? Because he’s the farthest thing from Barack Obama.

Obama fatigue has opened the way to Bush affection.

In all his recent interviews Mr. Bush has been modest, humorous, proud but unassuming, and essentially philosophical: History will decide. No finger-pointing or scoring points. If he feels rancor or resentment he didn’t show it. He didn’t attempt to manipulate. His sheer normality seemed like a relief, an echo of an older age.

And all this felt like an antidote to Obama—to the imperious I, to the inability to execute, to the endless interviews and the imperturbable drone, to the sense that he is trying to teach us, like an Ivy League instructor taken aback by the backwardness of his students. And there’s the unconscious superiority. One thing Mr. Bush didn’t think he was was superior. He thought he was luckily born, quick but not deep, and he famously trusted his gut but also his heart. He always seemed moved and grateful to be in the White House. Someone who met with Mr. Obama during his first year in office, an old hand who’d worked with many presidents, came away worried and confounded. Mr. Obama, he said, was the only one who didn’t seem awed by his surroundings, or by the presidency itself.

Mr. Bush could be prickly and irritable and near the end showed arrogance, but he wasn’t vain or conceited, and he still isn’t. When people said recently that they were surprised he could paint, he laughed: “Some people are surprised I can even read.”
