What can they actually do?
The entire state, from dog catcher to governor, is run by democrats. They can’t get any justice or fair dealings with them. The police and justice systems are rigged. They might as well be totally invisible, because the dems will just ignore them....................
About the only thing a California republican could do when they suspect voter fraud is to gather ‘evidence’ and go public with it. Go on any news org. that will have you on and start making noise about it. Be ready to defend your points.
The flip side, is one has to be ready to have your name, reputation, employment and personal intentions trashed or distorted by most of the media.
There is much to be risked by coming forward with what is obvious fraud.
