David Cameron has it all to do tonight

As I've said before each debate DC has it all to do. Tonight is his last chance. I know he can blow the others out of the water, but he has pulled his punches and I end up feeling that he has lost his chance to make a game changer.

He needs to be passionate, pin the economic disaster on Gordon Brown and say that it would be worse under the Lib Dems because we'd be in the Euro now. He needs to make the case for strong Government and end on optimism and power to the people.

If he can do these he might be able to make the game changer we need.

Also he needs to rebut the line 'taking money out of the economy' otherwise I might explode!

Squiffy.
