Jay Severin is on the Blaze talk radio (Net). Graham is on a network of stations run by Money Matters. Prog talkers like Jeff Santos, Steph Miller, Ed Schultz (at least on radio), Thom Harrtmann are the ones who are gone, but apparently Boston isn't a big liberal town

Or, maybe prog talk can best be found on powerful public radio stations. Why try 1510 when you have 89.7 and 90.9, and yes they ARE doing well.
Of course fans of classical, jazz, folk, and blues were a bit disappointed when those types of music were dropped by the NPR
stations in favor of news-talk but that's where THEIR revenue comes from. Yes, GBH bought CRB and now runs them, but now there's one classical station, not two. That's about to happen in Santa Barbara as KCRW is buying KDB and putting news-talk and other stuff on the 88.7 there (removing classical) but keeping classical on 93.7 KDB. One less classical station.
In Pittsburgh, WQED-FM is trimming their staff but doing what they can to keep classical on; WDUQ dumped jazz in favor of news-talk-NPR (now WESA) but a station in nearby W. Virginia is trying to replace the jazz lost by THAT move.
I will agree with Omnibus that E&B have their followers and probably put out a good product, for those who may lean that way. (Eagan is a bit of a moderate in some respects on the Herald staff...)
