The document posted and e-mailed by the McCain campaign on Tuesday night says at the end of its first full paragraph: “Lenders in these cases must recognize the loss that they’ve already suffered.”

So the government would buy the mortgages at a discounted rate, reflecting the declining value of the mortgage paper.

But when McCain reissued the document on Wednesday, that sentence was missing, to the dismay of many conservatives.

That would mean the U.S. would pay face value for the troubled documents, which was the main reason Sen. Barack Obama (D-Ill.) gave for opposing the plan.

A McCain campaign official explained the change: “That language was mistakenly included in the initial draft and it’s been corrected. It doesn’t reflect the intentions of the initiative, which necessitated the correction and the removal of the sentence. A simple mistake.”
