Hillary Clinton, Barack Obama, John Edwards & Bill Richardson meet with the executives of the American Federation of Teachers to answer questions culled from the membership.

Joe Biden has his AFL-CIO town hall in Opa Locka, Fla. (Video from Obama's similar event on Monday is here.)

Mitt Romney "Signs Up America" in Boston, Mass.
