As long as we have the electoral college, 15 million votes diffused across the nation, a few in some districts, more in another doesn’t necessarily affect the national outcome.
Only if they are targeting swing states and are able to shift enough votes to flip them can they affect a presidential election.
This is what the drive for the national popular vote is about. Making it easier for these asshats to steal elections.
Don't doubt that they did everything to help Hillary & she still lost!
