I know, there are so many to choose from, it's hard to pick just one. O'Reilly had his good points, as did 'Hardball' Matthews. Olberman's a good egg, and I think Hannity beats Colmes more often than not. Then, there are Couric, and whoever the other two are who round out the "big 3" network newschiefs.
But to get the ball rollin', I will pick the one who I trust most for the unadulterated news of the world: Jon Stewart.
