Yes, establishment repubs are critical of the president and always have been.  Most conservatives have been sticking with him because he has been doing the correct things.  He has been doing what he was elected to do.   It is understood that if you liked the racist policies of Obama, then you are going to be upset with him.   If you liked the big government policies where government controls every aspect of your life, you are also going to be upset with him.  Deal with it.
