I'll provide some lists below, there have been 159 promises kept just in the first 3 years. I'll mention a few of the promises that meant the most to me:
Ending the Iraq war and withdrawing our troops. McCain had stated he was fine with keeping them there 50, even 100 years as we did in Japan and Korea.
Ended the practice of torture.
Made the first step to transition to UHC with the historic health care reform.
Financial Regulation (although more is needed yet)
Middle class tax cut
Increased CAFE standards for cars and trucks
Reduce CO2 pollution
Historical funding of alternative and nuclear energy
Reduced unemployment
Repeal of DADT
