The rapid exploitation of the McCain "house" gaffe is very reassuring.  The attack was targeted, simple and easy to understand.  Granted McCain made it pretty easy (God, he really IS too old for the job) but the Obama media machine came hard and fast.  For a while I was worried they either could not or would not.  They are now attacking.  They need to avoid the defense.  I hope it continues.

Thus far during the campaign,  McCain has said remarkable number of stupid things.  Obama is now beginning to exploit them.  I'm encouraged.  Are you?
