Because the e-mails only focused on one candidate, and not others, someone came up with the idea that it  would be a good distraction to "blame the foreigners" (the Russians in this case) for interfering.  But should it be so surprising if only one candidate's e-mails are exposed?  People love to read about secret dirty tricks (remember that song "Dirty Laundry" by Don Henley? - not the Carrie Underwood song by the same name).  People wouldn't be bothered to read the bland information in the other candidate's e-mails.
