What would amendment convention propose in a hundred words or less worthy of our Constitution and withstand the test of time?

It is a mistake to call a convention to propose an amendment on campaign financing reform to resolve the Supreme Court’s  “Citizens United” free speech decision because one man’s free speech is another’s big money influence. Partisans declare George Soros, Labor Unions, ACLU and the Sierra Club  of exerting undue influence on one side and the Koch brothers on the other. The Roberts court is correct to retrieve free speech from the litany of campaign reform laws testing the intent and clarity of the First Amendment. And it is clarity that is the issue.  What would the convention propose in a hundred words or less as an amendment worthy of our Constitution that could withstand the test of time?
