After sweeping the March 15 primaries, Hillary Clinton transformed the democratic race. She not only solidified her position as the party's frontrunner, but also extended the delegate lead that she needed to pivot towards the general election.

While Bernie Sanders is in it for the long haul, the delegate math is not in his favor. His candidacy after the March 15 primaries could spell trouble for the Democratic Party, which will need to rally behind a single candidate to defeat Donald Trump in November. Clinton's success in a hypothetical general election will depend on her ability to win over Sanders supporters, which is much easier said than done.

According to the most recent Wall Street Journal poll, 33% of Bernie Sanders supporters wouldn't vote for Clinton. Sanders supporters have trust issues with Clinton and in particular, her Wall Street ties. Going forward, Clinton will need to carefully balance the fight against Sanders with the fight for his backers' support.

The only viable way Clinton can redeem herself with team Sanders is to release her Wall Street transcripts once and for all, thereby shaking out the remaining skeletons in her closet. If, however, Clinton refuses to come clean, we may very well be looking at a divided Democratic Party in the fall and a Republican President in the winter.
