Los Angeles Mayoral Candidate Spencer Pratt is holding nothing back in the next phase of his mission to save the once-great city of Los Angeles, announcing that he's staying in LA to retaliate after the rigged election for mayor.   Pratt emerged as an early leader in the primary for mayor, trouncing City Councilwoman Nithya Raman by about 40,000 votes on election night, but she staged a miraculous comeback with phony mail-in ballots.
