Here is an interesting article: "The reality supporters of Clinton and Sanders need to face":
An excerpt: "Right now all of these presidential candidates, both on the left and the right, are lying to everyone – all of them. They’re all making bold promises and statements based on power that, as president, they really won’t have. The truth is, a president can only accomplish what Congress will allow them to. This is what frustrated me so much following President Obama’s election. There’s such a misunderstanding among many Americans as to how government actually works that many Obama supporters turned on him prior to the 2010 midterms because he couldn’t wave a magic wand and make all of their hopes and dreams come true. Never mind that had liberals shown up in 2010, like they did in 2006 or 2008, President Obama could have accomplished much more than he was able to. But once Republicans seized the House – it was basically game over. .... So, while Clinton and Sanders supporters spend much of their time bickering over who should be the Democratic nominee, none of it is going to matter if liberals don’t show up in large numbers in November to give Democrats back at least some power in Congress. ...."
A major point is: if you're liberal or progressive, you HAVE to vote in 2016 and you should urge others to show up, too. If you're conservative, you may have concerns, too, because of the way the GOP is currently split among different "camps" and candidates.
And among the several online articles on Clinton and Sanders in the face of the Obama legacy, I found this one interesting: https://newrepublic.com/article/129721/barack-obama-can-save-hillary-clintons-candidacy
