"Senator Obama is the one candidate who has and will continue to expand the electorate beyond the traditional Democratic party base and bring young and new and Independent voters to the Democratic banner in November, an essential ingredient to a Democratic victory," Kirk said in a statement issued by the Obama campaign.
"America never turns back," he continued. "America always marches forward to seize the future. Eight of 10 Americans believe their country is on the wrong track. Senator Obama is the one candidate who, in the best tradition of American history, will not take us back but will lead us to a new future."
