The ACA, The American Recovery and Reinvestment Act, saved the U.S. auto industry, took out Bin Laden, The Consumer Protection Act, Repealed Don't Ask, Don't Tell in the U.S. military, The Credit Accountability and Disclosure Act, expanded Federal Wilderness Protections by millions of acres.... I can go on, whether you agree with his policies or not, the fact is you have to go all the way back to LBJ to find a president that was able to get more of their agenda enacted.
As to corruption, that is laughable. Your assertion is so ridiculous it sounds psychotic. Look at felony convictions of members of the Obama Administration and compare him to every other president in the entire post war era, he had the cleanest presidency of all of them. That is not to say they were without scandal, the IRS scandal comes to mind, but compared to any other president in the last 70 years, his administration was pretty clean. In comparison Trump is literally surrounded by felons, and Bush's Administration was so corrupt that you had high ups in the Department of Interior engaging in coke fueled orgies with oil industry lobbyists - no ****.
