Interestingly, Russia was supposedly trying to undermine trust in the US electoral process but there is no evidence of actually tampering with the vote. But now DHS will apparently be in a position to do so with no oversight.

Another issue is moving out of the realm of marginal conspiracy theory into the mainstream.
