Sen. Bernie Sanders isn't ready to give up.

In a memo to supporters following his big loss to Hillary Rodham Clinton in New York, in fact, he said that "we still have a path to the nomination."

Sisters and Brothers -

When we started this campaign, I emailed my supporters and said, "This campaign is not about Bernie Sanders. It's about a grassroots movement of Americans standing up and saying: 'Enough is enough. This country and our government belong to all of us, not just a handful of billionaires.'"

I believe that now more than ever.

We still have a path to the nomination, and our plan is to win the pledged delegates in this primary. Next week five states vote, and there are A LOT of delegates up for grabs. I am going to keep fighting for every vote, for every delegate, because each is a statement of support for the values we share. That's why I have to ask:

Can I count on you to add a $2.70 contribution to our campaign – right now – to help us win this primary and as a way of saying you will never stop fighting for the ideas that have powered our political revolution?

The truth is that if we stand together, there is no limit to what we can accomplish. We can bring hope to the political process. We can make real change. People should not underestimate us.

In solidarity,

Bernie Sanders
