Hillary Clinton came much closer to locking up the Democratic nomination on Tuesday night with big wins in Florida, North Carolina and Ohio, expanding her delegate lead to a potentially insurmountable margin for Sen. Bernie Sanders.

And for the first time, Sanders' biggest cheerleaders on the r/SandersForPresident subreddit seem to face that reality.

After months of organizing and raising money for Sanders, several appeared to come to the conclusion on Tuesday night that Sanders path from here is less than clear.

Following Tuesday's results, Clinton has nearly half of the delegates needed to secure the nomination, and Sanders would have to win the remaining states by wide margins to have any chance of catching up.

In response to peppy posts from Redditors who urged supporters not to be discouraged, many seemed dismayed about their candidate's path.

Perhaps the most damaging for Sanders' campaign, however, was the pessimism about future donations to Sanders campaign.

Sanders' bid has been fueled by small-dollar contributions — many of which came from money bombs launched by the r/SandersForPresident group.

If the grassroots network withers, Sanders could see his money begin to dry up ahead of costly contests in crucial states such as New York, New Jersey and California.

In a thread where a user posted an image of a $100 donation to Sanders' campaign, users responded by saying there were better ways to spend the money.
