SALEM, Ore. (AP) - Hillary Rodham Clinton is challenging her Democratic presidential opponent, Barack Obama, to two debates in Oregon in the run-up to the state's May 20 primary.

Clinton won a victory over Obama in Pennsylvania on Tuesday but still trails in the delegate count. She said Oregon voters deserve a chance to hear both candidates debate on the "real issues" facing the state.

"I encourage Oregonians to pay attention in the weeks ahead; to see how Sen. Obama and I address the issues that people in Oregon care about," Clinton said in a statement issued by her campaign.

Obama campaign spokesman Nick Shapiro said a decision will be made shortly about whether Obama will debate Clinton in Oregon. But Shapiro also said Clinton's call for more debates is "an old Washington game."

"There have been 21 Democratic debates and four one-on-one debates with Sen. Clinton, all televised nationally," he said. "Sen. Obama's focus is on meeting directly with Oregon voters about the issues that really matter to them."

Clinton's campaign spokeswoman, Julie Edwards, said there have been no presidential debates in the Pacific Northwest. She said last week's debate on ABC-TV was the most watched of the presidential campaign.

"There clearly is desire among voters to hear about the issues," she said.
