Doesn’t some of this have to do with timing of the buys? Obama campaign bought months ago. Romney could not spend money until officially nominated. Not certain of this, but I thought I read somewhere.
Couldn’t the RNC have bought the spots ahead of time to save money?
That would seem to only be the case if the Romney team had to actually pay for the spots ahead of airing. I don’t know, but that doesn’t seem to me to be probable.
