Why is there such a difference in the way Bush and Obama were handled?

When Bush went to war in Iraq (which at the time all major intelligence agencies agreed Saddam had WMD's) we were ailled with cries of liar, incompentent, --the office demeaned for 4 years or so--yet when Barrack tells us we can keep our docs (according to the head of the texas ama 67% of the docs will quit seeing medicare patients Jan 1 when the new provisions kick in)--he tells us health care costs will go down (12% up now on the average), tells us will save us money (costing us more)--tells us he will close Guantanomo (still open)--tells us his will be the most transparent presidency (even libs don't believe that one)--tells us we are not black, yellow, and white-but americans--and then turns out to be the most racially divisive president since woodrow wilson--how come we don't hear a murmer in the lame stream media about all these "lies"? Isnt there a little hypocrisy here at the minimum?
