Without evidence...I hear that all the time from liberals.  Evidence is what you 'collect' after you 'suspect' there might be reasonable or probable cause to investigate.  Trump and many others suspect there was fraud in California.  Evidence now must be collected to either prove or disprove the suspicions. First a random check of voter registration roles, cross referencing with the  ballots.  If the limited search turns nothing up, then there likely isn't  'probable cause' for a full  investigation
