In summary

Charter school advocates financed Antonio Villaraigosa’s campaign for governor with more than $22 million.

Wealthy charter school advocates spent $22.43 million in a failed independent campaign to get former Los Angeles Mayor Antonio Villaraigosa into the runoff for governor, and ended with a debt of $620,782, final campaign finance filings show.

Teachers unions and other labor groups teamed with a few wealthy donors, health insurer Blue Shield and Pacific Gas & Electric, to spend $6.6 million to help the top vote-getter, Democrat Gavin Newsom, campaign finance reports filed earlier this week show.

The pro-Villaraigosa campaign spent $16 million to boost the former LA mayor; $4 million to attack Newsom; and $1.89 million to muddy second-place finisher, Republican John Cox. Villaraigosa placed third, 840,000 votes behind Cox.

The biggest winners: television stations. Canal Partners, a company that purchases airtime, grossed $15.9 million but spent most of that on television ad buys.
