[A]t home, with Obama holding off his promised executive action on immigration reform, a new low of just 31 percent approve of his handling of immigration. Fifty-nine percent disapprove, up by a broad 18 points from spring 2013, when progress on the issue seemed imminent.

In general assessments, moreover, Americans by a 17-point margin say Obama has done more to divide than to unite the country, a rating worse than George W. Bush’s early in his poorly rated second term – and one that’s deteriorated among Obama’s supporters as well as among his critics. Just 43 percent call Obama a strong leader, down 11 points in the past year to the fewest of his presidency. And his overall job approval rating, at 42 percent, is a point from its all-time low this spring.

The risks to Obama’s party in the November elections are great – but they’re mitigated, all the same, by the Republican Party’s concurrent problems. While Americans by 55- 38 percent say Obama has done more to divide than to unite the country.
