Actually have been some McCain ads, including that one, on here lately, still massively outnumbered by the Obama ones ... which honestly I do not think are having any great effect at this point due to their tiresome repetition, except the "He's not Bush, but he DID vote with Bush 90% of the time..." ad, which is crying out for some kind of rebuttal, like:
"Dear Constitutional scholars of the Democrat party, President Bush does not vote on ANY legislation" or
"Senator Obama was only present for X% of the Senate votes since he was elected, but on the ones he was actually there for, he voted the same way a John McCain XX% of the time. Who's zooming who on this '90% same as Bush' stuff of Obama's?"
