It's a little known fact that Old Etonians represent an excluded minority, long persecuted and barred from office. At least, that is the message of David "Vote for change" Cameron. Taking President Obama's campaign message, and using it to get Conservatives elected is the latest phase in the silliness that began with Hague's "Conservative revolution" campaign ten years ago.
At a European level the Tories aren't well placed to make any change. They've withdrawn from their European Parliamentary bloc (the European People's Party). They're going to try and set up their own bloc Movement for European Reform. Essentially, leaving the biggest grouping in the Parliament to set up their own potemkin party.
Of course, for our fine feathered revolutionary Tories, they're content to see the European elections solely as a referendum on Gordon Brown's government. Polliticking games to get their arses on Government benches. The Party of peopel "born to rule" want to get back in their rightful place. That's the change they can believe in.
