Pan...its a stretch to hold either candidate responsible for comments or ads from persons or independent advocacy organizations with which they have no formal ties.
I'll give you an example that I think is worse than the above....and it is an official McCain campaign ad.
An
official McCain ad declares that Obama's only accomplishment in the Illinois senate was that he "backed legislation to teach "'comprehensive sex education' to kindergartners." The announcer then says, "Learning about sex before learning to read? Barack Obama. Wrong on education. Wrong for your family." (McCain: I approve this message)
IMO..you are just lookng for any jusitification to hold Obama responsible for any comment by anybody anywhere anytime.
