When Will President Obama Grow Up?

On Tuesday, President held a news conference about the economy and the unemployment problem. Instead of manning up and admit that some of the problems in the economy were caused by Obama and the Democrats, he continues to blame the GOP for the problems. http://www.foxnews.com/politics/2009/12/08/obama-takes-joblessness/?test=latestnews The GOP hasn't had any power for almost 11 months now. When will Obama grow up and start taking responsibility? He is like a little child that when caught breaking something, he blames someone else, like his brother or sister or saying I dunno. When will Obama grow up and stop acting like a 5 year old?
