What does 1 minute have to do with it? McCain has many millions he must spend prior to the convention so it being one minute is not out of the question. We’ll see if the ad just says it is from the McCain campaign or if it has “I’m John McCain and I approve this message” - if the latter, it is being run on TV.
He hasn't run a single ad over 30 sec yet. However I was wrong, "Passed Over" is 30 seconds not 1 min.
