Twenty-five Republicans are the targets of a new campaign by the Communications Workers of America attacking them for partially shutting down the Federal Aviation Administration in August over disagreements on union rights.

The FAA got shut down because [House Transportation Committee] Chairman John Mica [R-Fla.] and some [other] Republicans would rather play politics with real people’s lives and the FAA Reauthorization bill, CWA states in the mailer it sent as a large piece of the campaign. At the request of their big corporate airline donors, like Delta, Republicans snuck unrelated union provisions into this critical legislation. Then Congress took off on vacation and shut down the FAA.

Besides Mica, many of the Republican House members targeted are freshmen from swing districts.

The full list: Paul Gosar (Ariz.), David Schweikert (Ariz.), Dan Lungren (Calif.), Mary Bono Mack (Calif.), Randy Hultgren (Ill.), Bobby Schilling (Ill.), Tom Latham (Iowa), Andy Harris (Md.), Erik Paulsen (Minn.), Chip Cravaack (Minn.), Frank Guinta (N.H.), Charlie Bass (N.H.), Leonard Lance (N.J.), Joe Heck (Nev.), Nan Hayworth (N.Y.), Richard Hanna (N.Y.), Tom Reed (N.Y.), Jim Gerlach (Pa.), Mike Fitzpatrick (Pa.), Lou Barletta (Pa.), Charlie Dent (Pa.), Blake Farenthold (Texas), Jaime Herrera Beutler (Wash.) and Sean Duffy (Wis.).
