That's because that's when folks will be paying attention. Romney will be buying lots of ad time during October, as well.
Well, yeah. But the issue is (as you stated) people are not paying attention to what Romney has said in the past and my response was that there are videos out there which I'm sure Obama will use to expose Romney's multiple choice of every issue.
Regarding Romney's october ads (which are irrelevent to what we're talking about) it would be nice to see him use those ads to say more than "vote for me because I am not Obama". Is this man another McCain or what? I mean, all I'm hearing on the news is "Romney's trying to run against President Obama's healthcare which was based on his own healthcare in Mass" and "Romney's the most secretive candidate since Nixon".
Time to put on the gloves now before he's defined FOR the American people by the opposition. Once defined, it sticks.
