Political parties and other interest groups pumped another $2.8 million over the past week to support or oppose candidates in California's hottest races for Congress.
The groups are not contributing directly to candidates' campaigns but are buying TV ad time, sending mailers or bankrolling other efforts to influence the outcome of the Nov. 4 elections.
The spending must be reported to the Federal Election Commission, within either 24 or 48 hours, depending on the circumstances. Groups are not allowed to coordinate with campaigns but must make their spending decisions independently.
The Democratic Congressional Campaign Committee was a close second, spending nearly $863,000 on efforts to beat back Republican candidates in four races.
Democrats also spent money against Republicans in two other close races--one in Ventura County, where Rep. Julia Brownley is trying to fend off a challenge by Assemblyman Jeff Gorell of Camarillo, and the other in the Inland Empire, where Redlands Mayor Pete Aguilar, a Democrat, is vying with Republican Paul Chabot, a military veteran, for an open seat.
