You could make similar claims about say The Guardian, or people who get their news from Reddit. Personally, I find the echo-chamber on the left to be far more worrying (Not to mention their constant condescending sneering, looking down on the "idiot" masses).
Look at Reddit at the moment.. endless discussion about how the only reason anyone could vote for Romney is "uneducated voters".
In this case, both graphs look completely stagnant. Perhaps The Daily Mail did choose their start date to tie the numbers up nicely. Maybe they even rounded the start and end figures so that they could claim the numbers are exactly the same. But whichever way you look at it, the graphs are stagnant.
