CHICAGO — Obama for America has released a new web video, because today, the choice in this election became even clearer. On one side is a candidate who has disdainfully written off half the country. On the other, a President who has always said we can only change Washington together—and we have. The American people have worked together to fight for student loan reform, equal pay for equal work, expanded access to healthcare, Wall Street reform, ending the war in Iraq and turning the tide of the greatest economic crisis since the Great Depression. But the job is not yet finished. As President Obama knows, we must work together to change Washington and we’ve already come too far to turn back now.
