Neither compares. Franken doesn't have 40 million people behind him...and Maddow can't touch Limbaugh in terms of followers.
I repeat:
NPR has TWO daily news/commentary shows that get approximately the same size audience as Limbaugh.
So in other words you're admitting NPR is liberal talk radio.
NPR is decidedly left of center, but not extremely so. But I don't believe NPR's most popular programs run opposite Rush or Hannity which would be necessary to do an honest evaluation of whether they could draw the same audience. Also I don't believe Arbitron includes NPR in its rating service, so whatever numbers are being reported are likely not from Arbitron.
In any case it doesn't matter. It does raise the question though that if public radio is so popular, why is it necessary for we taxpayers to subsidize it via mega millions every year? Why can't it stand on its own as a private enterprise?
And as for those who are now including personal attacks on me as well as Rush, I am honored. When they start the ad hominem and personal insults, you KNOW you're on the right track with the lefties, are reporting what they can't refute, and they have nothing else.
