This isn't really a good comparison to make. Obama was the Sanders of the last election, he just wasn't as extreme and his sandersism was mostly created by inexperience. People aren't happy they voted "Sanders" in the form of Obama and got "Clinton" instead last election, and they aren't going to be happy about it this year either.Barack Obama got the votes of 92 percent of Democrats in 2012, and she'll be in the same neighborhood.
This is a very accurate critique. Even though I voted Obama, I now wish that Clinton would have won the previous election, because (although we wouldn't have my man, Sanders running) Obama would be available to run during this election and I think he would have made a much greater difference running AFTER Hillary, instead of before. Clinton was already pretty close to being a burnt out shill in the previous election, and now she perfectly embodies that, but I think she essentially would have done the same things in office that Obama did do during this administration, and then Obama would have the chance to come in and be a liberal superhero and champion a lot of the things that Sanders has latched onto. But that's alternate history.
