Is it wise for Obama to take economic advice from a former CEO (1999-2004) & a former chaiman of Fannie Mae? ?

Obama needs an advisor? I thought he was an expert in all things economic. He STILL criticizes McCain for saying that economics isnt his strong suit. I dont think it matters anyway. Obama seems to me to be SO arrogant that he wouldnt listen to anyone that disagreed with him. He is going to do what he wants to do regardless of what the real experts say.
