And in campaign news, Democratic presidential candidates gathered in Philadelphia last night for their first debate in over a month. Front-runner Senator Hillary Rodham Clinton came under repeated criticism for her record on the Iraq war, trade agreements and torture. Senator Barack Obama accused Clinton of changing her stance when politically convenient. Clinton also came under criticism for voting in favor of a Senate resolution designating Iran’s Revolutionary Guard as a terrorist group. Critics see the measure as a possible authorization for military attack on Iran. The debate excluded former Alaska Senator Mike Gravel. Organizers say he did not meet fundraising and polling requirements.
