Bernie Sanders should subordinate to the Clinton platform at the Democratic Convention for the sake of party unity. Although he fought valiantly and surpassed expectations, he still lost. It is much more important for the party to work to get her elected rather than Donald Trump, who will destroy any semblance of Sanders' agenda.
Now that Bernie Sanders improbable run for president has come to its likely end, he should organize and help lead the party by calling for unity. If Bernie sanders were to come out an cast his support behind Clinton, it would go a long way to ease the pain of the primary season and most likely help Clinton int he fall.
While Bernie Sanders has clearly enjoyed sparring with Hillary Clinton over the course of this campaign, it is time for him to set those arguments aside and move forward for the good of the Democratic Party. If he supports her platform at the Democratic Convention, this will be an incredible gesture that will show his followers that personal differences are not nearly as important as party unity.
Yes, that is what politics is about.It is all about playing the game. Bernie may get another turn one day, but this is not his time. He needs to just sit back and relax and the party do its thing to win the election. Sometimes it best not to be the squeaky wheel
