Retired Gen. Wesley Clark's comments casting doubt on how John McCain's military experience prepares him for the presidency must have really irked the Arizona senator. The campaign is up today with a new ad that couldn’t make any clearer the "Love" (subscription) McCain feels for his country -- and how this patriotism qualifies him to be president over Barack Obama.

The ad opens with images of 1967’s "Summer of Love," complete with hippies protesting the war and frolicking with each other. The announcer then shifts into a more somber note: "Half a world away, another kind of love -- of country. John McCain: Shot down. Bayoneted. Tortured." Speaking over pictures of McCain serving in Vietnam, the announcer stresses how the Republican's patriotism has shone through during his time overseas and his years in Congress. "His philosophy: before party, polls and self -- America," the announcer says.

The spot then makes a direct attack on Obama's infamous "change we can believe in" rhetoric and "hope" slogan. "John McCain doesn't always tell us what we 'hope' to hear. Beautiful words cannot make our lives better." The ad concludes with one more jab at the Democrat: "Don't 'hope' for a better life. Vote for one."

While the Illinois senator has been accused of flip-flopping on a number of key issues, including his stance on the Iraq war, McCain has capitalized by highlighting his comparably steadfast and consistent record on the war.
