Here's coverage from TPM Election Central:

The drumbeat of good Hillary news just isn't stopping today: The latest is that she's picking up the endorsement of the American Federation of Teachers.

Garance Franke-Ruta at Tapped offers this analysis:

The move was long expected for three reasons: Clinton's historic commitment to and advocacy work around the education of children have given her deep relationships in the education community; the largest AFT affiliate is based in New York; and more than three-fourths of teachers are female.

Marc Ambinder at The Atlantic reports, "a union source says the vote for Hillary was 'overwhelming.'"

Liz Benjamin at Daily Politics looks at the timing:

The New York contingent, which is the largest state organization in the AFT, lobbied hard on the part of its "favorite daughter" - a status the union conferred on Clinton back in April - while Illinois, the second-largest, did the same on behalf of its designated "favorite son," Barack Obama.

The argument, Ianuzzi said, was less about whether Clinton should be the AFT's candidate, since 45 percent of the union's likely voters favor her, according to a poll conducted by Peter Hart Associates (Obama got 21, John Edwards received 13), and more about whether it would be more appropriate to delay the endorsement altogether to see if some other frontrunner emerges.

The Council isn't scheduled to meet again until February, Ianuzzi noted, by which point, at the rate things are going, the Democratic nomination contest could be good and over.
