Both I and most Congressional Republicans want to defund NPR. Republicans want to do it because they perceive it as a government-funded liberal partisan voice; I want to do it because broadcasting is simply not a role for government.
But note -- Republicans who want to count coup on NPR out of spite and frustration should recognize that defunding it could very likely make NPR a more, rather than less, potent leftish voice (insert Star Wars quote "if you strike me down.... yada yada). NPR's government funding is all that is really keeping it in sight of the political center. Pull that funding and it will be free to tack left - in fact, this likely will be an imperative given its likely sources of additional private funding it will need.
All of which is fine by me, but I think the Republicans are expecting an Air America-type crash and burn, and I think they are mistaken. There is a lot about PBS and NPR that are vital and unique -- their supporters are not wrong about that -- which I think will make them viable private (though still non-profit) entities.
