My mother just called to let me know George W. Bush was on Oprah. I squirmed for a moment, wondering if it was worth sacrificing my ability to say "I've never watched Oprah" in order to hear the former president. But I only caught the latter half, so I can still claim not to have seen a full episode....
I note that President Bush has always conducted himself as a gentleman. Even as President Obama futilely continues to blame Bush for his every hardship and failure, his successor refuses to respond with an unkind word.
It's noteworthy that the Bush years were not plagued by any credible personal scandals. The inability to seize WMD's was an embarrassment, while revelations of enhanced interrogation techniques and the NSA wiretapping program caused a national controversy, but none of these were scandals in the sense that Bush had acted immorally or unethically in an objective sense. Liberals may not have liked his policies, but they were undertaken with good intentions and complied with established laws and norms (where such existed). The man did not act for personal gain, abuse his position or surrender his convictions. Those virtues will forever demonize him in the eyes of his adversaries, but I expect he sleeps well at night.
