To a large extent yes. I doubt anybody running for president will be as good of a president as Obama has been.
Clinton has my vote, but she has weaknesses that make her far from my ideal candidate. While I agree with Sanders on many issues, his strategy of hoping for a political revolution to push his agenda through is too divorced from reality, not to mention he wouldn't run a good general election campaign.
You have got to be kidding me on Obama being a good President? I guess being dishonest, abusing power, prolonging a recession and cutting deals with outlaw regimes is your definition of a "good President" but it sure as heck isn't mine.
You seem confused, you're talking about George Bush
