SIOUX CITY | A fourth Democrat is entering the race for Iowa governor. Paul Dahl, of Webster City, plans to launch his campaign in Sioux City on Saturday.

Dahl has worked much of his life as a librarian, and will incorporate stops at libraries as he undertakes his campaign announcement swing. He will begin with an 8 a.m. appearance at the Wilbur Aalfs Library, 529 Pierce St.

Dahl describes himself as a moderate Democrat. He ran for an Iowa congressional seat in 1994, but lost in the primary to Sheila McGuire. In Woodbury County, Dahl got 105 votes, McGuire received 2,072 and Mike Peterson had 1,317.

"There is no greater honor than to be a public servant pursuing compassionate public policies improving the quality of life for one’s neighbors while also living in a harmonious interdependence with the ecological world around us,” Dahl said in a statement.

Dahl said key issues in Iowa are agricultural revitalization, expanding renewable energy, tax reform and directing more funding to education.

Of the Democrats running, Dahl is the only candidate without legislative experience. Candidates Tyler Olson and Jack Hatch are in the Legislature, while Bob Krause is a former lawmaker.

Dahl has degrees from the University of Iowa and University of Northern Iowa. He works as a bus driver for a governmental agency in Webster City and as a sales associate for a retail business.

Gov. Terry Branstad, a Republican who has served five terms, hasn't confirmed he is running for re-election, but has hired campaign staff and is raising money.
