Here is a new ad from the Obama campaign attacking John McCain and defending Joe Biden during the now infamous "there's not gonnabe six month before the president is tested" statement.
In a very smart way, the ad insists on the fact that Biden added:
"They're going to find this guy's got steel in his spine."
And balance Obama's steady hand with McCain's eratic behavior.
It's good to see that Obama can also respond to attacks through ads and not only through their surrogates.
