Unfortunately, there isn't and objectivity world wide. I was ecstatic to final get CBC when I got the Roku. Most of their national news casts and Daily Show like programming is very subjective. Much of which is their objection of the Canadian government "following the American government".
As I said a well informed opinion is a well researched one. I will painstakingly listen to both Liberal and Conservative talk. As an Independent, each side brings something to the table. We just need to sift through there garbage to get that nugget of sense making. Yesterday I thought a liberal on local radio sounded like an idiot, where two days ago I thought they made perfect sense. The same holds true for the conservative I listen to.
