Whilst the press are undoubtedly skewed towards us the broadcasters aren't. I would be interested to know how much the newspaper bias really matters anyway.
After all if you are reading the Mail/Sun/Express/Times/Torygraph you probably aren't a Labour voter anyway. So I kind of doubt that the biased press has as much impact as you (or they) think.
Eh lot of people read the tabloids even if they aren't that politically engaged. There's the famous statistics that there are more Labour Voters who read the Daily Mail than read the Guardian.
