Yes, Hillary Clinton is going to beat Bernie Sanders and become the Democratic presidential nominee because she holds a commanding lead over Sanders in terms of delegates and is closing in on the number needed to clinch the nomination. Sanders has been a more formidable opponent that most people expected and has also helped bring important issues to the forefront, but I believe that Clinton is definitely going to beat him in the next couple of months.
Hilary will get the nomination. This is because she has so much name recognition, and certain voting blocs, like middle-age and elderly black Americans tend to vote for her. Bernie Sanders seems to get the young white voting bloc. However, Hilary also gets the general woman vote as well. These will put her ahead of Bernie for the nomination.
Bernie Sanders has put up a great fight, and I applaud him for trying. However, Hillary Clinton has too many supporters, especially from within the establishment, for Bernie to beat her. Clinton has nearly half of all the delegates that she needs to win the nomination already, with Bernie holding less than half as many as her. It would take a miracle for Bernie to catch up at this point.
It seems like Bernie supporters are trying to paint an alternate reality for themselves that is really, really sad. Hillary is winning large states. Hillary is winning diverse states. Hillary is blowing out states by bigger margins in most, but to be fair, not all of the states where Bernie wins. Bernie Sanders is a formidable candidate. But he's not going to win unless something significantly changes in the race. Right now, it doesn't look like that's going to happen.
