The contest to find the Democratic presidential candidate is a bit like buses; you wait for one good contender and two come along at once.

With Hillary Clinton expected to back Barack Obama on Saturday, it’s raised expectations that she could be the perfect running mate.

And find out why a prisoner has been enjoying his home comforts in his cell.
