Why does Tony Blair have his own Election 2010 campaign website?

Well it was clear the former Prime Minister Tony Blair would have some role to play in the Labour campaign for the upcoming election after making a speech in his home constituency of Sedgefield on Tuesday, but why does he now have his own election campaign website?

Unless I, as well as all the mainstream local, national and international media have missed something, Mr Blair is not seeking re-election this year... so his website - tonyblair4labour.org - which was actually produced by Blue State Digital, the same developers that made the hugely-successful website for a certain Barack Obama - seems a little odd.

As you would expect the site contains news, videos and social media interactivity tools... but still, why does it exist? Any ideas...?
