First disappointment and first mistake's Obama...Rahm Emanuel?

I'm a democrat and I do not like Rahm Emanuel. He is not a team player nor a partisan "lap dog". He is a danger to Obama's team unless Obama is strong enough to keep him on a leash. Everything in Emanuel's world is secondary to himself. He is a strong and capable politician and will not be happy being anyone's second or third banana. Makes me wonder what Obama was thinking when he chose him
