No, actually, we can't. The Alaskan state gov has timed the ethics investigation to go off as an October surprise, and Obama has a 30 member squad of slime-sifters on the ground. Relaxing before it's over is sending your guy to address 250,000 adoring Germans and planning an event in an 80,000 seat venue instead of researching every possible VP pick your opponent could come up with.
Relaxing before it's over is what has given McCain/Palin this opportunity.
Not to doubt you prognosticating prowess, but I really don't know how good your kung-fu is.
The "ethics investigation" isn't going to uncover anything in a month. Whatever is going to be drummed up is already known, and they'd be leaking/running with it now if it was worth anything. Plus, there's already a big public preception that the other side is throwing everything and the kitchen sink against Palin, and it's repetitive, and none of it's sticking.
But I do agree, you never relax in a fight like this.
