For the American Federation of Teachers, Hillary Clinton’s concession on Saturday means that it’s time for the union to repair any lost love and throw its full support behind Barack Obama. Although the Obama campaign will certainly appreciate the AFT’s organized foot-soldiers, the union will have to work a little harder to wield any influence since it spent the last several months aligned with Clinton—and is a late-comer to the Obama bandwagon.

Unlike the National Education Association, at least the AFT endorsed a candidate when it still mattered.
