The guerrilla tactics include vows to try to oust Clinton supporters from office or threats to withhold funding from the Democratic Party.

But superdelegates reached by The Washington Times said they won’t be bullied.

“It goes with the territory. I have thick skin. But you’re not going to [get] people like myself to support your candidate by making threats,” said Ken Martin, chairman of the Minnesota Democratic-Farmer-Labor Party and a superdelegate backing Mrs. Clinton.

He said he receives between 10 and 20 threatening emails daily and gets just as many abusive phone calls, which he said were spurred by a Sanders supporter posting his cellphone number online.
