I think it’s part of the strategy. Let Obama do himself in. Let him spend his money in states he didn’t think he’d have to. Let Obama go on the attack while McCain rises above it and looks more Presidential. As Palin said in her interview last night: the American people are not stupid - they know what’s going on. If you noticed in the last round of ads from McCain, the media played it up as “back and forth” attacks and tried to deligitimze McCain’s ads. Let him save the money and go in for the kill later.
If you consider this as a pick up basket ball (someone already compared it. I am just extending on it), we are in second quarter. I think Mccain is saving his energy for the 4th quarter (Oct16-Nov 4). By that time, Fed will do something to get the economy back. O’man would have bled all his money in Florida and in PA,MI, WI to defend. He would be literally broke. At that time, Palin will cover O’man one on one and McCain will make some easy lay ups. Biden will call a non-existent time out. Palin will make a technical free throw at the last minute (She actually did it in a match during her play days). I think McCain is leaving O by himself to self-destruct.
