Not the ones I respect (Ron Wyden for example).
Also I'm fairly certain, had conservatives been actually serious about budget cutting, the funding for NPR (and the condemnation of Teachers/unions) wouldn't have been brought up as a serious issue, considering it's small potatoes compared to the real waste of tax money and the structure of the system.
But they're easy targets, and people can beat their chest and be proud that they found someone/something to blame for the issues instead of actually trying to fix it. I liken it to complaining about your car running bad and getting horrible gas mileage, and then proclaiming you found a major reason why, and replace the light bulb in the dome light. After all, it shed light on the situation!
If we're going to claim that NPR shouldn't be funded due to the reasons shooter wrote (or the other reasons listed/referred to), then I'm afraid we should be cutting the funding on a LOT of stuff. But what happens when we do that? It makes it worse for the society, because we can't afford to fund a lot of stuff that the government does for us. If you take away a lot of the public funding of things, you leave it solely for the wealthy who can afford it.
And I don't believe NPR has a "liberal slant", as much as some people are so conservative they think anything 1 degree to the left of them is "too liberal". But I might as well be yelling at the clouds when trying to get certain factions of politically active people to use their logic brain instead of their sheep brain.
NPR/Public Broadcasting gets very little of their total budget from the Government (which creates an argument for both sides of the coin here). The amount they get doesn't mean that the government any say. And if we're going to go off of the "funding" issue, and control/influence, there is a lot of funding the government does that is far worse influence. Also, if we're going to bring up what is in the constitution for what the government has to fund, we're going to have to cut a lot. AND if we're going to follow the constitution closer then we do, we might have to start arresting former Presidents, and cabinet members for violating it. And we didn't really get a declaration of war from the congress till after we were already there.
So, there's always that.
