saying we've got to fight for our interests in washington. >> greta: i don't know why they are so concerned. our research has shown they've spent 4.8 million dollars on lobbyist this year it is not like they have no voice. now, gm says that it is not gm making the contributions but it is their pac. it is employees contributing to pac. the big question is what employees? concentrateed to any sort of economic strata? >> usually the top executives. i wouldn't be surprised if it isn't gm. there's a limit at the top. somebody on the assembly line isn't gonna fork over $5,000. that's something very easy for gm executive, even after the bailout to do. usually these political action committees -- are funded by top executives who have the compensation to spare.
