Boy howdy!!! I got the one wrong and the other depends upon which scoundrel you believe.

Regarding the cost of the war, a White House representative said it would cost in the neighborhood of $50 billion to $60 billion, and Bush's economic advisor was fired for saying it could cost $200 billion. Neither of those was Bush, however.

Regarding casualties.

"Robertson, an ardent Bush supporter, told CNN in an interview Tuesday night that he urged the president to prepare the American people for the prospect of casualties before launching the war in March 2003.

"Robertson said Bush told him, " 'Oh, no, we're not going to have any casualties.' "

The White House denies Bush saying that. I have a hard time believing Bush on anything, and doubt Robertson would have made it up.

ER has it right below. The country was led down the primrose path on that war by the Bush Administration. Estimates of costs and times were orders of magnitude off, lie followed lie in order to generate fear, and we all know it.

And I was wrong on Bush estimating the cost. That was a henchman. I would say I'm right on the claim of no casualties.
