I think most Americans (even if they describe themselves as conservative) get all of their information from the TV. They sit there and are passively brainwashed. Literally. Liberally (pun intended).
The Dems have taken advantage of this, to great effect. Ultimately this strategy of state sponsored media will backfire on them, as even regular folks are learning to distrust the MSM.
It takes more effort today to educate oneself and uncover the truth. You simply cannot flip on the boob tube or pick up the daily local paper. Most folks simply do not have the time, or do not care enough to do so.
Of course, anyone reading this does not fall into that group!
THIS is what liberal dominance of the media does: people swallow left-wing ideas and don't realize that they are supporting radical ideas and putting themselves in opposition to the ideas that made this country great.
