Questions over FiveThirtyEight’s future come as Silver faces public criticism for his reliance on polls that inaccurately predicted a “red wave” in the midterm elections.

“There’s no question in my mind that FiveThirtyEight was used by partisan sources to create a false impression of the election and that Nate was aware this was happening and by not addressing it he ended up contributing to misleading the American people about what was happening in the election,“ Democratic strategist and former ABC News producer Simon Rosenberg told Confider. “This is an existential threat to FiveThirtyEight. If he refuses to make significant reforms and changes the political elite should move on to other sources to get information about polling.”

Silver did not respond to a request for comment, but an ABC News spokesperson texted Confider: “There are no imminent decisions about our relationship with 538.”
