Each state gives equal money to each person running for any office. That is all they get. No outside money from another state or policical group is allowed. The state controls the elections, it can stop the corruption. Taxpayers pay for their own state elections. Very simple
Why is this important?
It doesn't take a high IQ to figure out how to stop corruptiion. Make the states control their own elections. Why should any outside money be allowed to influence your states future? The Supreme Court judges think we are too stupid to fix their mess, I am betting that we aren't.
