Amid these growing scandals, Pombo faced serious primary opposition for the first time since his initial race in 1992. His leading opponent was former congressman Pete McCloskey, a leading moderate Republican. Earlier, McCloskey had led an effort to find a viable primary challenger to Pombo. Pombo defeated McCloskey in the primary with 61 percent of the vote. McCloskey had been endorsed by "The Sacramento Bee", the "San Jose Mercury News", and the League of Conservation Voters. Seven weeks later, McCloskey endorsed Pombo's Democratic opponent, Jerry McNerney, who had won the Democratic primary over Steve Filson and Steve Thomas. McNerney received just over half of the Democratic vote and faced Pombo in the 2006 general election in November. McNerney had been Pombo's opponent in 2004.
