POLITICAL talk show hosts.
Radio and television talk shows included.
The O'Reilly category includes all the usual pro-Bush types like Rush Limbaugh, Ann Coulter and Laura Ingraham. (I assume that stuff like the McLaughlin Group and News Hour with Jim Lehrer is too boring for most of you to tolerate, and please note the prejudice of such programs leans in the same direction as Limbaugh and O'Reilly.)
The other category includes Bill Maher and other "liberals" (Al Franken, Michael Moore, Now on PBS, etc). Bill Moyer's televised investigative journalism reports also belong in this category.
If anyone seriously advocates any legitimate "third Party" talk show hosts which do not reasonably fit into one of these two categories, then I will include try to incorporate them ina subsequent poll.
