<p>WASHINGTON — In a variation on an old theme, a Hispanic supporter of Howard Dean called a Latina Republican Senate candidate a "house Mexican" who is not being true to her race.</p>
<p>Steven Ybarra, a Democratic National Committee (search) official and regional coordinator of Latinos for Dean (search), called Rosario Marin (search), the former U.S. treasurer under President Bush who is now seeking the GOP nomination to compete against California Sen. Barbara Boxer, a "house Mexican for the Republicans." The attack was sent out in a mass e-mail to political activists, community leaders and a number of journalists this week.</p>
