"My expectation is that we will continue to try to ratchet up the pressure on the president to change course," the Democratic presidential candidate said in an interview with The Associated Press. "I don't think that we will see a majority of the Senate vote to cut off funding at this stage."
Given that Bush is determined to veto a timetable for withdrawing U.S. troops from Iraq, Congress has little realistic choice but to approve money for the war, Obama said.
"I think that nobody wants to play chicken with our troops on the ground," said Obama. "I do think a majority of the Senate has now expressed the belief that we need to change course in Iraq.
"Obviously we're constrained by the fact that a commander in chief who also has veto power has the option of ignoring that position," Obama said.
