ABC News' David Wright reports from Cartagena, Colombia. Sen. John McCain has set himself a difficult task on his trip to Latin America: to score political points against rival Barack Obama without criticizing him directly.
"I believe that partisanship ends at the water's edge," McCain said emphatically, when asked about Obama at a press conference at the Colombian Presidential retreat here.
But on the inaugural flight of the Straight Talk Express - airborne edition - McCain felt freer to let loose.
. . .
McCain bristled at the comments on "Face the Nation" last weekend by an Obama supporter, retired general Wesley Clark, who belittled the relevance of McCain's wartime experience as a qualification for the Presidency.
"I think it's up to Sen. Obama now not only to repudiate him but to cut him loose," McCain said.
McCain became visibly angry when I asked him to explain how his Vietnam experience prepared him for the Presidency.
"Please," he said, recoiling back in his seat in distaste at the very question.
