Clapper and McCain are anachronisms stuck in the Cold War of the 1950's.  "Fear the Reds!"  "The Bear is Coming!"  They need to curl up in their backyard underground bunkers and not come out again.

BTW: When people hack they use anoymizing Internet gateways, that conceal source IP addresses.  If JimBob in Newark, NJ wanted to hack the DNC mail server, he would go through an easily available Russian anonymizer server to hide his identity.  But of course, by doing this ... it wouldn't be JimBob from Newark doing the hacking.  The Dems and the likes of Clapper and McCain would track to the Russian server and be convinced it was those "dirty Red bastards".
