So bad so who would want to lead the party

Alex Barker over at the Westminster blog believes that for now the Prime Minister is safe

Earlier this evening, a despondent enemy of Gordon Brown explained to me why the prime minister’s position is safe.
Labour’s situation is so bad, it has left the rebels without a cause. There was hope last summer that new leadership could revive the party’s fortunes. Now not even the most zealous critic of Brown believes Labour can win a fourth term. You can see why someone would risk rebellion to lead Labour to victory. But which senior figure will lead a mutiny for the sake of damage limitation?
