Spencer Pratt’s sister criticizes his candidacy for mayor of Los Angeles

Spencer Pratt might have a ton of supporters supporting his bid for mayor of Los Angeles…but his sister Stephanie is not one of them – because she warns people not to elect her!

Stephanie took to social media Saturday to bash her brother’s political ambitions… admitting he’s done a great job for the Pacific Palisades community — but he can’t be responsible for 4 million citizens.

Spencer is only running to boost sales of his memoir “The Guy You Loved to Hate: Confessions of a Reality TV Villain,” Stephanie claims…and she’s telling people to wait and see what he does with their tax money if he’s elected.

Stephanie writes that she is worried about Los Angeles – referring to the mayor Karen Bass as “ASSBASS” in office – but adds that the city doesn’t need “another unqualified, inexperienced mayor. Voting for him is a vote for stupidity.”

Spencer announced his race for the mayor last month… mainly speaking about the local government’s mismanagement of the Pacific Palisades Fire which burned down his house among many other structures in the region.

We spoke to Spencer at a campaign event last week, and he’s confident he can defeat Mayor Bass – who he calls Karen Basura, trash in Spanish – mainly because he’s sure she’s going to end up in jail for obstruction of justice. Much of his comments seemed taken directly from the President Trump political playbook

However, if he wants to move into the mayor’s residence, the Getty House, Spencer may have to settle the discord himself.

We’ve reached out to Spencer…so far, no response.
