AFL-CIO officials will be barnstorming the country on behalf of Democratic candidates during the Labor Day weekend.

President Richard Trumka will appear Sunday with Gov. Ted Strickland (D) in Ohio.

Secretary-Treasurer Liz Shuler will campaign Monday with Jerry Brown, the Democratic candidate for governor of California, while Executive Vice President Arlene Holt Baker will campaign over the weekend in Florida, a state featuring a series of key congressional races plus a Senate race and gubernatorial race this fall.

Two of the states are important this year because of the governor's role in the redistricting process — Ohio is predicted to lose two House seats after the 2010 census is complete, while Florida is expected to gain one. California is predicted to remain the same but the state has some of the largest union memberships in the country. 

All three states will be important in the 2012 presidential race.

On Labor Day, Trumka will be in Milwaukee for a rally with President Obama and Secretary of Labor Hilda Solis.
