Obama losing control of his own party?

Over the past few months and especially past few weeks, the control Obama has over the Democrats of Congress has been questioned. Now, in a recent vote against a tax cut bill Obama was trying to pass, this control is shown to be lacked even more than thought. There have been many other articles indicating that Obama needs to change the way he is running his own party; otherwise, it does not seem that he will remain in office as President. I find it to be a matter that could go both ways. Obama could change what he is doing and gain back the complete loyalty of the Democratic party, or he could continue down the same path and lose all loyalty.
