For evangelical leaders the election of GWB was the epitome of everything they wanted in a president, and what they insisted the country needed to restore "morality" to American life.  For all the talk about this being a "Christian nation," very few, if any, American presidents referenced Jesus Christ in speeches, etc.  Even God was sometimes given a neutralized "Creator" description.  

You know, another little "fun fact" is that Obama invoked Christ MORE than GWB.  DJT has thus far rarely referenced God or Jesus...and when he does, it seems to embarrass any and all believers, as it ought.
