make all political campaigns funded by public money derived from federal general fund.

Good government will come when the money is out of politics. Congress spends half their time raising funds for re-election from donors that expect a return on their investment. Public funding would end this. Also, as a condition of maintaining their license to use our airwaves, broadcasters must donate a percentage of the air time before an election to candidates who meet a certain level of community support. This will also help curtail the"buying of an election". $7 annually per person times 300 million Americans nets $2.1 billion per year to elect leaders that will work for the American people and not special interests.
Revenues could be collected from various sources, including tax returns, license renewals or tariffs.
