U.S. Sen. John McCain's campaign has begun airing an ad critical of U.S. Sen. Barack Obama's stance on the Iraq war.

The thirty-second ad, entitled "Troop Funding," began airing today on WMUR and is airing in ten other battleground states.

"Barack Obama never held a single Senate hearing on Afghanistan. He hasn't been to Iraq in years," the announcer states. "He voted against funding our troops. Positions that helped him win his nomination. Now Obama is changing to help himself become president."

The ad comes on the eve of Obama's overseas trip includes stops in Germany, Jordan, Israel, France, the West Bank and Great Britain.

Next week McCain is scheduled to host a town hall forum in Rochester.
