Several major Iowa labor unions are endorsing Democratic State Sen. Jack Hatch for governor. Iowa AFSCME Council 61 announced their backing for Hatch Thursday, along with four local Teamsters unions. AFSMCE represents about 40,000 workers in state and local government, schools and some private jobs. Hatch says he expects the unions will offer financial and volunteer support. Hatch is the leading Democrat seeking the nomination for governor. He will likely face Republican Governor Terry Branstad, who is running for a sixth term.
