Whatever miniscule chance he had is now officially toast.

More from the Socialist Worker’s piece:

…But in running for the Democratic presidential nomination as the liberal outsider with almost no chance of winning, Sanders isn’t very “bold”–no more so than the fizzled campaigns of Dennis Kucinich in past presidential election years. And by steering liberal and left supporters into a Democratic Party whose policies and politics he claims to disagree with, Sanders–no matter how critical he might be of Hillary Clinton–is acting as the opposite of an “alternative.”

The recent uprising in Baltimore proves this. Without that revolt, the Baltimore state’s attorney would never have charged the six cops who killed Freddie Gray. Without more struggle, they will certainly not be convicted.

At the same time, the left shouldn’t abandon the electoral arena to the two capitalist parties. If we do, we create a vacuum that the Democrats will fill, co-opting movement activists, demobilizing unions and social movements, and redirecting their precious time, money and energy into electing candidates who then betray workers and the oppressed.

We need to win the new left born out of Occupy, public-sector union struggles and the Black Lives Matter movement to breaking with the Democratic Party and building an electoral alternative as a complement to struggle from below. Bernie Sanders’ campaign inside the Democratic Party is an obstacle to that project.
