Right after the election, I think it was, Trump’s COS at the time Reince Priebus, in an interview, said that the RNC computers had not been hacked. He said they had hired security techs to equip their computers against hacking, etc. The same service was offered to the Rats, but declined.
This is the more important reason to remind voters that Russia targeted both parties.
Because the wall analogy is so perfect, I assume Trump will employ it sooner or later for mid terms.
Which party can protect America elections? The party that values walls and firewalls and which successfully protected itself in 2016? Or the party which wants a southern border as porous to sovereignty-poison as the open cyber borders of the DNC/Hillary servers?
