If you don't have the support of the base, you won't be the nominee.

69. First Sanders never had a chance of being the nominee and second, the oppo would have killed him

Sanders never had a chance of being the nominee. Sanders was rejected by Jewish, African American and Latino voters. Sanders did not have the support of the base of the party. There was no way that Sanders would be the nominee unless he could get the support of the Jewish, African American and Latino voters are key elements in the base. The support of mainly white voters are not sufficient for Sanders to be the nominee in the real world.

Second, Sanders was never really running to win. After Super Tuesday, it was clear that Sanders would not be the nominee. Hillary Clinrton had a delegate lead that Sanders could not over come. Sanders was not really running to be the nominee but to get attention

Second, even Sanders admitted that he was running for media coverage and money http://www.politico.com/blogs/2016-dem-primary-live-updates-and-results/2016/03/bernie-sanders-independent-media-coverage-220747

Bernie Sanders on Monday told NBC’s Chuck Todd that he ran as a Democrat to get more media coverage.

During a town hall-style event in Columbus, Ohio, the independent Vermont senator said, “In terms of media coverage, you have to run within the Democratic Party.” He then took a dig at MNSBC, telling Todd, the network “would not have me on his program” if he ran as an independent.

Money also played a role in his decision to run as a Democrat, Sanders added.

“To run as an independent, you need — you could be a billionaire," he said. "If you're a billionaire, you can do that. I'm not a billionaire. So the structure of American politics today is such that I thought the right ethic was to run within the Democratic Party.”

Third, Sanders would have been killed by the oppo research Trump had an oppo book on Sanders that was two feet thick. http://www.newsweek.com/myths-cost-democrats-presidential-election-521044

They ignored the fact that Sanders had not yet faced a real campaign against him. Clinton was in the delicate position of dealing with a large portion of voters who treated Sanders more like the Messiah than just another candidate. She was playing the long game—attacking Sanders strongly enough to win, but gently enough to avoid alienating his supporters. Given her overwhelming support from communities of color—for example, about 70 percent of African-American voters cast their ballot for her—Clinton had a firewall that would be difficult for Sanders to breach....

So what would have happened when Sanders hit a real opponent, someone who did not care about alienating the young college voters in his base? I have seen the opposition book assembled by Republicans for Sanders, and it was brutal. The Republicans would have torn him apart. And while Sanders supporters might delude themselves into believing that they could have defended him against all of this, there is a name for politicians who play defense all the time: losers....

The Republicans had at least four other damning Sanders videos (I don’t know what they showed), and the opposition research folder was almost 2-feet thick. (The section calling him a communist with connections to Castro alone would have cost him Florida.) In other words, the belief that Sanders would have walked into the White House based on polls taken before anyone really attacked him is a delusion built on a scaffolding of political ignorance.

Trump would have destroyed Sanders in the general election
