Even I could think up a dozen very effective ads against Clinton. And $500mil worth of those will change some votes.
As Hillary has been launching TV ad salvos at Trump, he has more than held his own -- even gaining defecting black and Dem voters -- while not even launching what will undoubtedly be an aggressive and devastating ad campaign.
And if we consider the effect that$100m-$500m of Trump ads will have -- an anticipated efficiency quotient of at least 3-1 over The Hag's lame ads -- she'll really be hemorrhaging votes.
