No. Of course John McCain didn't say anything of the sort. It's gutter politics to even suggest it. In honoring the courageous passengers of United 93, McCain said:
“No American living then, should ever forget the heroism that occurred in the skies above this field on September 11, 2001,” McCain said, referring to the passengers who wrested control of the plane that may have been intended to crash into the Capitol.
“They, and possibly I, owe our lives to the passengers who summoned the courage and love necessary to deprive our depraved and hateful enemies their terrible triumph.”
Under the current McCain rules, the fact that the terrorists intending to crash United 93 into the Capital or White House were deprived of triumph means, perversely, that the terrorists who struck the World Trade Center and the Pentagon must have triumphed.
But, damn it, it's too ugly even to pretend. Some things should above politics. Like terrorist attacks. And protecting kids from pedophiles.
