Are there any Democratic radio talk show hosts, and if so who.?

Answer 1

The most famous recent one that jumps to mind is Al Franken. Web link to his show is below.

Answer 2

Not so much Democratic, but progressive and intelligent:

Air America is a nationwide network airing shows like Al Franken and Randi Rhodes. Locally I listen to a progressive station which airs local guy Jay Marvin as well as Rachel Maddow, Jerry Springer (yes, that Jerry Springer - he's a hoot!), Ed Schultz and the Majority Report with Jeanine Garrafalo and Sam Seder.
