Obama salvaged the economy but he has not been able to make it soar. I do give him credit for that but a great many people suffered in 2008 and they aren't as well informed as you and I. I view the Democrat's social agenda as both distractions and preaching to the choir. Everything has a cost. Obama also has been pretty bad at cajoling the GOP congress. you can argue that it is not his fault, but Bill Clinton managed to work with the GOP congress probably because he had been a former governor and also because he is white and is better at ingratiating himself with other white politicians. Obama would run into the wall and just stay there, not working to get past it.
Reagan for instance never agreed with the Democrats in Congress, but they liked him. I can't say the same for Obama. I voted Obama btw but I've always thought this was a weakness of his which was problematic for governing.
