Obama considers Iraq visit amid criticism of foreign policy experience

Barack Obama - increasingly under fire from John McCain as he appears poised to win the Democratic nomination - said he is considering a trip to Iraq but dismissed as a "political stunt" an invitation by the Republican candidate to make the visit together. McCain and Obama have increasingly targeted each other as a November general election showdown between the two men seems inevitable. The discussion about Iraq, largely sidelined during the primary battle, is likely to factor prominently in the general election and Obama has rallied to counter McCain's criticism that he lacks foreign policy experience. Obama, who is now just 44 delegates shy of the 2,026 needed to claim the nomination and drive rival Hillary Rodham Clinton out of the race, could win the White House nod as early as Sunday if he fares well in Puerto Rico's primary.
