Take a look at some of the Chromecast videos on YouTube and you may change your mind. What I noticed is that once I installed my Chromcast we spend less time on Fox News and more time on YouTube. A big advantage of that is instead of spending 1/3 of your time watching commercials you get to watch whatever you want that 99.5% commercial free.
Another point about YouTube: Much of the newer content is true HDTV - 720P or 1080P so it looks great on your HDTV. And there is plenty of political content.
If you are getting tired of O'Reilly and Hannity you should give it a try.
In that vein, I recommend any YouTube video with John Taylor Gatto. A very wise man.
I fully agree with Diana in Wisconsin's point made here.
