Why do politicians prefer cash basis?

Since I've seen this same question twice recently, I have to presume this is homework. You should be showing us some attempt at doing your own work first.

I'm also not aware that politicians do prefer a cash basis. If someone has a reference to this fact I'd love to see it.

The other thread I posted on is here:
