Nate Silver believes Clinton could've won if the FBI letter didn't come out

Nate Silver believes that Comey's letter hurt Clinton's chances to be President.

He tweeted

There's more evidence, too: Late-deciding voters broke strongly against Clinton in swing states, enough to cost her MI/WI/PA. pic.twitter.com/8r801ahDQO

"I'll put it like this: Clinton would almost certainly be President-elect if the election had been held on Oct. 27 (day before Comey letter)," Silver tweeted.

Comey in October sent a letter to lawmakers about the discovery of new emails the FBI said were potentially relevant to the investigation into Clinton's use of a private email server while serving as secretary of State.

The emails were reportedly found during a separate FBI investigation into former Rep. Anthony Weiner (D-N.Y.). Weiner is the estranged husband of one of Clinton's top aides, Huma Abedin.

Republicans and members of Donald Trump's campaign seized on the new information, attempting to cast Clinton as corrupt and praising the FBI for the development.

Then just days before the general election, Comey announced the FBI had not changed its July conclusion not to bring charges regarding Clinton's private server.

Since the election, Clinton campaign officials have put blame on Comey for the Democratic nominee's loss.

"There are lots of reasons why an election like this is not successful," Clinton told donors on a conference call one week after the election. "Our analysis is that Comey's letter raising doubts that were groundless, baseless, proven to be, stopped our momentum."
