After the debt ceiling debacle and his statements that everyone should stay on the summer recess so they don't just come back early and pissed off it doesn't look good to do this on the first evening back and during the GOP debate (although it is one of MANY debates coming up).
It will be easy to paint him as an uncooperative shit disturber which is exactly the opposite of what every politician should be wanting at this point.
The rep debate has been scheduled for quite some time. This was nothing but a cheap stunt by Obama, who can't resist throwing his ego around. I know that those on this board that felat Obama in their dreams will never see it this way, but it is what it is.. Obama doesn't need to make this speech before a joint session of Congress; this was just an attempt to diss reps in their own house. BTW, it's the Speaker's place to invite Obama, not Obama's place to demand an audience. There's still this silly thing in the Constitution about separation of powers, you know.
And as for the speech? Unless Obama has concrete ideas on how to spur job growth in the private sector, all we'll have is yet another big spending bill. Sorry, your messiah loses again.
/waits for the Obamaphiles to howl, yowl, whine, and blame Bush.
