John Dingell, D-Dearborn, who has been in Congress for 50 years, knows how to keep up with the kids. He’s introduced a podcast, The Dingellcast, joining a growing number of politicians that are using podcasting to communicate with their constituents.”I’m not going to kid anyone, I don’t have an iPod, but I see them all over the place,” Dingell said. “This is one more way to satisfy what seems like a boundless appetite for news from Capitol Hill. We want people to know what is happening here.”
