California Rep. John Garamendi (D) led his Republican challenger by 15 points in a new poll conducted for a Democratic-aligned super PAC.

Garamendi led Colusa County Supervisor Kim Vann 54 percent to 39 percent. The two are running in the redrawn, Sacramento-area 3rd district, which became more competitive after redistricting.

The poll of 400 likely voters in the district was conducted August 26-27 by GBA Strategies on behalf of House Majority PAC. It had a margin of error of 4.9 points.

The Democratic Congressional Campaign Committee released an internal automated poll last month that showed Garamendi ahead by 15 points.

Roll Call rates the race as Leans Democratic.
