waste of money

I am not comfortable with the amount of money that goes into campaigns. I think that there should be a by law that cuts down on the money. Say someone raises 1 billion dollars, and they don't use it all. The extra money should be put into our national debt so that it's at least a little better. they don't need 1 billion dollars though so they shouldn't try spending it all. it's almost disgusting how much they spend on the elections
