What percentage of the country do you believe would agree that Sarah Palin actually said, "I can see Russia from my house"?
Ronald Reagan was elected in a day and age that didn't have the kind of media saturation as we see today. And, he was elected when media - to include the entertainment business - wasn't NEARLY as politicized as it is today. It is, in many ways, apples & oranges.
Virtually every television show on today, and MANY movies have an obscene level of politically slanted content. Look at this list of movies nominated for Oscars and compare the movies in 1970s to the movies in the 2000s. Not until the late 70s, do we start to see a real emergence of political movies, and all of them are anti-war type movies - about a war that is LONG over. Today, Hollywood makes anti-war movies about a war that is still being faught.
Look at the list from 2005. Everyone one of those movies has at least some political message, or is entirely about a political message.
I could go on, but for a variety of reasons, I think the media is MUCH more powerful and influential today than it was in the 1970s and early 1980s. Contrary to popular sentiment, the MSM is not dying.
That's just not so. The media has always been liberal, always biased and always against conservatives, at least since the LBJ Great Society days. There were left-wing movies made in the 60's and 70's too, more in fact. Vietnam anti-war, green propaganda, Soviet apologism and more.
The one thing that is constant and predictable in American politics is the liberalism of the media. It's simply a given.
