As for the single Republican in this, I don't have access to the transcript yet, but it sounds like Lugar is simply telling Bush to take charge more.

In fact the entire extent of his quotes on this subject is "The president has to be the president, over the vice president and over these secretaries."

This is extrapolated by MSNBC into President Bush is facing new criticism from Democrats and some Republicans who think the administration is not speaking with one voice on Iraq. And of course, the headline of "Senators Denounce Bush Iraq Policy" is a masterpiece of twist, implying bipartisan condemnation of Iraq policy in general, when in fact mostly Democrats were heard, and most of what they said was about administration authority, not Iraq policy.

Notice the persistent fantasy that if only France would help us out, everything would be fine.
