To say the obvious: There is great risk of the FBI and/or Comey trying to influence the outcome of the election. Earlier, when Comey said Clinton had been "extremely careless", it seemed to overstep his bounds: He played judge and jury, and convicted her without trial.

To do this two weeks before the election raises very serious questions about the U.S.'s most fundamental institutions, rule of law, and democracy. Every Democratic leader is subject to endless investigation and deligitimization.

EDIT: This is not a partisan concern. Everyone needs these institutions, democracy and the rule of law.
