DES MOINES — Iowa Republicans have opened a new front in the campaign for governor, charging Monday that Democrat Fred Hubbell is running from the truth about his time as chief executive of Younkers.The attack is based on the closure of Younkers stores in smaller communities while Hubbell was the retail chain’s chairman from 1985-92.Hubbell “put profits over people and made decisions that kicked working people to the curb,” according to Republican Party of Iowa spokesman Jesse Dougherty.The Hubbell campaign called it an attempt to divert scrutiny of Republican Gov.
