Sunday Conversation: McCain's New Ad

Barack Obama may be stealing most of the media coverage with his trip abroad but John McCain isn't sitting back and ceding ground to the Illinois senator.

McCain is up with a new ad that blasts Obama for his lack of foreign policy experience and his changeability when it comes to key issues including the war in Iraq.

Here's the ad:

"Barack Obama never held a single Senate hearing on Afghanistan," says the ad's narrator. "He hasn't been to Iraq in years. He voted against funding out troops."

Those "positions" helped Obama secure the Democratic party's nomination, according to the narrator, but "now Obama is changing to help himself become president."

The ad closes by noting that McCain "has always supported our troops" and the surge in Iraq. "McCain: Country first," the ad ends.

It's the first major contrast ad of the general election and hits at a fascinating time given Obama's trip abroad.

But will it work?
