From First Read:

*** They’ve Done Studies, You Know — 50% Of The Time, It Works Every Time: As of yesterday, President Obama’s approval rating in the Gallup daily tracking poll was 52%, which is close to the 51% in our NBC poll from last month. As Gallup has noted, if Obama falls below 50% in his eighth month on the job, it will be the third-fastest drop below that mark for a new president since World War II. Gerald Ford fell below 50% in his third month, Bill Clinton in his fourth month, Ronald Reagan in his 10th month, Jimmy Carter in his 13th month, Richard Nixon in his 25th month, LBJ in his 29th month, Bush 41 in his 36th month, Bush 43 in his 37th month, and Eisenhower in his 63rd month. Note: Kennedy never fell below 50% before he was assassinated, and George W. Bush was approaching that mark right before the 9/11 terrorist attacks. A few things to remember about all the analysis folks will see on polls in the coming days: There are more BAD polls now than ever before; it confuses the issue and lets some folks cherry-pick what they want. The VERY erratic robo-polling firms have added to the confusion like never before.
