Stalking Horse?

I don't have an opinion yet on the campaign for governor between Gavin Newsom, Antonio Villaraigosa, John Chiang and Delaine Eastin, but the entry into the race of Amanda Renteria, a former Hillary Clinton campaign staffer, is suspicious at the go. Who enters a major race 30 days before the filing deadline with no campaign infrastructure, no staff, no website, no endorsements, and no cash? It's not a stretch to think that Renteria will be on the ballot to suppress support of Newsom's chief rival Villaraigosa among Latinos. Is this another attempt by the party poobahs to rig a primary outcome? Shouldn't the voters get to hear from the candidates before the fix is in?
