From today's Washington Post:
When Edward P. Lazear, chairman of the White House Council of Economic Advisers, broached the idea of limiting the popular mortgage tax deduction, he said he quickly dropped it after Cheney told him it would never fly with Congress. "He's a big timesaver for us in that he takes off the table a lot of things he knows aren't going to go anywhere," Lazear said.
Lazear, who is otherwise known as a fierce advocate for his views, said that he may argue a point with Cheney "for 10 minutes or so" but that in the end he is always convinced. "I can't think of a time when I have thought I was right and the vice president was wrong."
