Murdoch has an unfailing nose for sniffing the winds of political change. His easy switch of The Sun’s allegiance to Blair in the 90s shows his good judgement – he backs winners and breaks losers. Although Blair is a busted flush now and irrelevant to his future interests, he seems to be letting Rebekah Wade’s Sun become increasingly rabid in its support of New Labour despite the unpopularity of Blair. It’s like Pravda with tits today.

Blunkett’s columnn is a classic attack on Brown by proxy; “There are some people who blame Tony Blair for the latest ruckus. Come off it! Of course he takes responsibility. But does anyone REALLY think that in the middle of an 18-hour-a-day election campaign he has the time to ask about every contribution “Is this a loan or a gift?” You might just have thought that this was the job of the party treasurer, Jack Dromey, who suddenly became aware of it and went into quite a tizzy.”

When Murdoch senses Cameron is likely to win he’ll fire Rebekah and put in someone more sympathetic to the Tories. That will be a more reliable indicator of the election result than any poll.
