Only Nixon could go to China, as the saying goes.
EDIT: I don't mean this in terms of electability -- I think Bernie can beat Trump hands down. What I mean is accomplishing what he sets out to do in terms of policy implementation -- which, as the Obama years have shown us, is not as easy as it sounds.
Tied in Iowa, won popular vote
Polling strong in Nevada.
The momentum is there.
EDIT: Regarding policy, with so many Supreme Court Justices up in age, the next President will likely get the chance to set the tone. Citizens United is the ruling that enabled much of the financial influence in the government, and Bernie is committed to dismantling it.
Terrible strategy. Bernie replacing Ruth Bader Ginsberg and Stephen Breyer isn't going to advance the agenda. Clarence Thomas is only 71 and won't step down if a Democrat is president.
The only way Bernie passes his agenda is by getting significant portions of the country to strike until Congress complies.

Pretty much what Trump did to Republican resistance, but doubtfully as amazingly successful as it's been for Trump.
Something of note that Obama did is turn over an enormous movement to the DNC when he assumed office. Not sure anyone knows why except insiders, but it was definitely his biggest mistake, and neutered his clout. (https://newrepublic.com/article/140245/obamas-lost-army-insi...). No chance Bernie will do that.
Bernie's answer to your question would probably be "I can't, but together we can." As cheesy as it sounds, it's true.
