Did any of those sources make a big announcement that they have super-duper incriminating emails about a candidate and then slowly release them in a trickle over the course of 30 days leading up to the election? Emails which, by the way, were so boring and mundane and contained so little evidence of misconduct that people determined to hate Clinton needed to treat "pizza" as secret code for "child sex slaves", to extract a scandal from them.
