Conor Friedersdorf, writing in the Atlantic, marvels not that Obama's approval rating is "only" 42%; he says it should not be even that high [via Ralph]:
[H]ere's what I find alarming: Confronted with a president who 1) spied on every American; 2) covered up torture; 3) continued a War on Drugs ruinous to minorities and whole foreign nations; 4) killed hundreds of innocents in drone strikes; 5) waged war illegally and killed an American citizen without due process (while suppressing the legal reasoning used to do so); 6) let high-ranking national-security officials break the law with impunity; and 7) persecuted whistleblowers—confronted with all of those transgressions, more than four in 10 Americans still approve of the job Obama is doing. And most of them are loyal Democrats. Partisanship and tribalism are overriding the moral compass of too many liberals, who ought to be furious with Obama. National-security policies he unilaterally pursued will be harming the U.S., its moral standing, and its most vulnerable citizens for years if not decades to come, especially since Democrats are poised to make civil illibertarian Hillary Clinton their party's next leader.
And these points do not include his cozying up with Muslim fanatics, Benghazi, the devastation of health care for so many people now reduced to part-time jobs, and the cronyism with Goldman Sachs and others on Wall Street.
