You're are absolutely correct. The left has mobilized for a century. They have sent their minions into all levels of government, even small town city councils.
If we are ever going to root that evil out, we are going to have to do the same thing. I just today found out about 2 organization calleds "Labor Community Strategy Center" and "National School for Strategic Organizing". These are where ordinary citizens become leftist community organizers. I am guessing that those community organizers are then sent all over the nation.
