They say that the long primary fight with the independent senator from Vermont, which looks like it could go all the way to the Democratic convention in Philadelphia, has taken a toll on Clinton’s standing in the polls. In the latest RealClearPolitics average,she is two-tenths of a point behind Trump, the presumptive GOP presidential nominee.

The surrogates say they’re concerned that Sanders is still — this late in the game — throwing shots at Clinton and the Democratic establishment.
“I don’t think he realizes the damage he’s doing at this point,” one ally said of Sanders. “I understand running the campaign until the end, fine. But at least take the steps to begin bringing everyone together.”

In an interview with ABC on Sunday, Sanders called voting for Clinton in the general election “the lesser of two evils.”

He has also kept up a steady drumbeat of criticism against the Democratic National Committee and its chairwoman, Rep. Debbie Wasserman Schultz (D-Fla.), who his supporters charge is rigging the contest against Sanders.

A series of polls over the weekend all point to a tightening general election race between Trump and Clinton, who needs 90 more delegates to clinch the Democratic nomination, according to The Associated Press.
