SIOUX FALLS, S.D. (AP) -- Barack Obama's turned his full-bore attention to the general election contest against Republican John McCain.
While Hillary Rodham Clinton mounted a likely last hurrah in Puerto Rico and national Democrats resolved the sticky issue of seating Florida and Michigan delegates under a formula favorable to Obama, the Illinois senator took a series of bold steps to signal his focus was riveted on the fall campaign.
Among them: he severed ties with his Chicago church and politically meddlesome pastors who've preached from its pulpit. And his campaign announced a stop at site of this summer's GOP convention in St. Paul, Minnesota.
Meanwhile, he's stepping up his criticism of McCain, pummeling him on Iraq, Iran and veterans matters.
The primary season ends Tuesday.
