Tonight at the Capitol Hill Club, a long list of lobbyists will host a fundraiser for Rep. Dan Lungren (R-Calif), who is in a competitive race for reelection this year. Many of these lobbyists have hosted events for Lungren in the past, and represent some of his biggest campaign donors.

In all, 19 lobbyists themselves have donated nearly $30,000 to Lungren’s campaign fund since 2004, based on Party Time analysis of federal campaign finance records. Their firms have also donated more than $133,000 through their Political Action Committees (PACs), and many of their firm’s clients have also donated to Lungren over the course of his career.

For example, one of the event’s hosts, Barney Skladany, of the lobbying firm Akin Gump Strauss Hauer and Feld, represents high-profile clients including AT&T and Johnson & Johnson, two of Lungren’s top donors in this election. Skladany also represents The Dow Chemical Company, the Corrections Corporation of America, Delhaize Group, Liberty Mutual and PG&E Corp, all of which have donated to Lungren through their PACs.

Other hosts for tonight’s event include Shannon Campagna, who represents Safeway Inc., James Norton, who lobbies for General Dynamics, and Tom Boyd who represents DLA Piper. All of these companies are top donors to the Lungren campaign, according to the Center for Responsive Politics.
