Tom Rielly, an Oskaloosa Democrat, also announced his endorsement for

political action committees or federal lobbyists "prove to me he'll
bring much needed change to Washington D.C."

Elesha Gayman of Davenport. State Sen. Robert Dvorsky of Coralville.
Also, Attorney General Tom Miller and Treasurer Mike Fitzgerald.

Dvorsky endorses Obama Thu 6.28.2007
Sen. Bob Dvorsky, a Coralville Democrat, has endorsed Barack Obama for
president.

"Senator Obama had the wisdom to oppose the war in Iraq from the
beginning and the courage to speak out against it when other
politicians wouldn't," Dvorsky said in a statement. "He has spent his
time in the U.S. Senate fighting to bring our troops home, and I
believe he's our best hope to bring an end to the war in Iraq and
start focusing on diplomatic solutions."
