Marc Thiessen thinks he's caught BHO in dereliction of his duties by not attending PDB meetings on daily basis. I think Marc states that BHO has only attended 40% of them. Let's think about this for a minute.
GW Bush took his PDB's orally almost daily, without failure. Why? He preferred this method over reading. By the way, a lot of good those verbal PDBs were in thwarting 9/11, but I digress.
Ronald Reagan read his PDBs 99% of the time. Marc likes to say that Reagan and BHO aren't comparable because we live in post 9/11 world. Excuse me.... the COLD WAR we were living from 1947 - 1991 makes the war on terror look like Romper Room.
The bottom line is, there is no structure - formal or informal, to the PDB. All Presidents receive them in writing. Some like to have a meeting to discuss them, especially if you are a grammatical idiot as GWB is. BHO has opted for a mix. BHO like any other President gets briefed on a daily basis in the manner of their own choosing.
The only advantage the right can see to have BHO personally attend a meeting is to get him off the campaign trail. Good luck with that!
