How do you figure that this is her fault?
When your campaign fails to execute on the same very basic responsibility three times in a row, the candidate has fallen down on the job.
When the ad failed to run for the second time at the 10:00 slot, there should have been a team of angry and litigious O'Donnell staffers and volunteers in the TV station offices demanding and confirming that the 3:00 spot would run.
Instead, her campaign's response is: "It didn't get done. We don't know why. Maybe they forgot."
Am I going to vote for someone who is basically saying: "the dog ate my homework"?
