Now, people who read the Independent tend to be well educated people who make an informed decision on how to vote. The Sun has a reading age of 7. What impact will a well researched article hidden in the pages of the Independent have on the public compared to the front page of The Sun which stands out of the newspaper rack and broadcasts its message even to those who don't read a paper?
The answer is obvious. Then there's the Mail, circulation 1,437,541 weekdays, 2,246,196 Saturday. This is today's front page.

He has an uphill struggle with the entire weight of the Media establishment against him. They finished off Michael Foot and Neil Kinnock.
In 1992 the Labour party under Kinnock were riding high in the polls. This is the Sun front page on the day of the general election.
John Major won with a slim majority and the Sun was quick to take credit. The front page the day after the 92 election.
