McCain vs Obama in their first debate

In their first head-to-head debate Friday, Sen. John McCain criticized Sen. Barack Obama as a candidate who "doesn't understand" the key issues the country faces, and Obama linked McCain to President Bush on several issues.

"I'm afraid Sen. Obama doesn't understand the difference between a tactic and a strategy," McCain said as the two traded jabs over Iraq.

Obama shot back, "I absolutely understand the difference between tactics and strategy. And the strategic question that the president has to ask is not whether or not we are employing a particular approach in the country once we have made the decision to be there."

McCain drew from his experience overseas as he tried to portray himself as the more qualified candidate.

"Incredibly, incredibly Sen. Obama didn't go to Iraq for 900 days and never asked for a meeting with Gen Petraeus.
