Limit campaign contributions to only those individuals, individuals, and conglomerates inside the US who pay their taxes to the US.
Why is this important?
I am now aware of the fact that many campaine donations come from outside the United States. Donators have influence over the candidate they support and there fore should not be able to influence our government. No wonder companies allowed unless they are tax payers. Rather individual, business or conglomerate only those within the US should be have offices outside of the US. If those companies could not contribute to campaines they would have a reason to have their offices inside the US and pay their taxes here.
