I see the opposite. Many more channels of communication nowadays.
Perhaps you should listen to Ronald Reagan speeches. He was indeed the best speaker I've ever seen in a candidate. Also, the fewer channels means fewer choices which means less opportunity to miss a Reagan speech or debate.
Obama's skill is to put long college words together and make them sound good to the many shallow people out there listening and voting. They think he's so smart when he talks.
You and I know he said nothing but we have a lot of shallow people who think he said something meaningful when he really said nothing at all. Obama's a pro at lies and he's like a lawyer. He can get the murderer off and make the murderer appear to be the victim. That's what we're dealing with in debates with this man.
