You're neglecting the fact that Reagan's policies led to a growing economy and real job creation - which then caused his approval level to increase.
Obama's policies are dampening economic and job growth. Hence, there won't be similar drivers to improve his approval levels.
AFTER he raised taxes. lol..
you still don't get it.
Regan said a lot of things... and not one of them was implemented.
but he sang a lot of happy horse manure that made you people sit up and beg.
his reality wasn't near his legend. in fact, he was a horrible president, with horrible policies.
he talked nice, though.
