What does Bernie Sanders have to do in order to win the 2016 Democratic Party presidential primaries and take part in the 2016 general election?

Answer 1

As of February 2016, Bernie Sanders appears to be leading in most Demographics of the Democratic Party. Whatever his current strategy is, it seems to be the one most likely to propel him to victory in the Democratic primary. Whether it will serve him well in a Presidential election depends entirely on which Republican is his adversary.

--Update--
As of March 2016, it is clear that Bernie Sanders is not effectively courting the Black and Latino communities. In order to be victorious, he would have to embrace the kind of race-baiting that Hillary Clinton engages in, in order to bring these groups on his side. Ultimately the last few primaries that he lost were lost on account of the Black vote.

Answer 2

Senator Bernie Sanders is seeking the Democratic Party's nomination for the office of US president. In order to receive this nomination and run in the 2106 US presidential election, he must win a sizable amount of delegates in the Democratic Primaries. So far he has won the New Hampshire primary and ran a close second in the Iowa Caucus polling.
