Functionally, Clinton will clinch the nomination on June 7. That's just reality

44. I partly agree but mostly disagree. Here's why:

You are correct that Hillary may well clinch the nomination on June 7. That we agree upon.

Yet there are a number of reasons why it is advantageous for the Sanders-led movement, for the Democratic Party, and for Hillary that Sanders continue to campaign and, if necessary, to raise platform contests at the convention.

How does the continuation of the Sanders' campaign help Hillary? Several ways:

The ongoing Sanders campaign gives Hillary an avenue to dominate news cycles with a story other than her email server problem or whatever bullshit twitter post Trump launched the previous day - this prolongs Hillary's opportunity to discuss how her platform will help the middle class and those aspiring to join the middle class;

The ongoing Sanders campaign gives Hillary a foil against which she can cast herself as the Goldilocks "middle choice" between Trump on her right (at least on domestic issues) and Sanders on her left;

The ongoing Sanders campaign gives Hillary a prime time event to make her general election pitch in a forum worth tens of millions of dollars worth of TV ads - it is crazy to pass up on the California debate, which is a golden opportunity in the Golden State to hit a huge audience with her general election message.

How does the continuation of the Sanders' campaign help the Democratic Party? Several ways:

The ongoing Sanders campaign gives the Democratic Party an opportunity to restore the enthusiasm we will need in the Fall if we are going to have a chance at avoiding a Trump administration - the party would hugely benefit from a vigorous debate about party rules (who wouldn't have some of their faith restored by the reform of a process where lobbyists super-delegates are installed to impose their will over grassroots voters?), the party platform (wouldn't it help with Hillary's key weakness by fighting the perception that Hillary is rudderless to adopt a platform that enshrines her shift to the left during the primary?), and the best role for the FDR-Sanders-Warren wing of the party (imagine how much easier it would be to retake the Senate if we empowered he Sanders-led movement to tap its energy on behalf of our Senate candidates in New Hampshire, Colorado, and Wisconsin?);

The ongoing Sanders campaign gives the Democratic Party an opportunity to find common ground - while Sanders continues to get push-back from the party and from Hillary on important progressive issue, of course he will continue to fight for these goals, but you hear more and more Sanders (and Warren) attacks on Trump, and this helps unite the party.

We are Democrats and this is democracy. Democrats should not fear democracy.
