Some of these news people and politicians have had to work hard to make it to the top and some have not. JFK and George Bush Junior did not have to work hard to make it as president due to their families status. Theodore Rossevelt and Harry Truman had to work hard to make it to the top of the political ladder.
The problem is that people forget who they were and how they got into a certain position. Then when a person receives a political position such as senator or president, then the culture in these positions start to thwart their good intentions.
Now with web-based media, politicians have a greater chance of providing a canned or a staff member response to constitutes. This makes them harder to reach and give the people of a country the illusion of communicating with their elected public officials.
