Not a single policy, it's meant to elicit an emotional reaction out of low information voters like you, and look, it worked!
How can you change a corrupt system by taking its money? You didn't answer the question.
Obama could have worked to change campaign finance laws when he was president, but he didn't because he took money for his election bid from big donors who benefit from the current campaign finance laws. Why would we expect that to change? Why would those big donors fund the campaign of a politician who's big on changing the laws to ensure they can't buy government? Seems like a pretty straightforward question, do you have the spine to answer it?
“You have to go where the money is. Now where the money is, there’s almost always implicitly some string attached. … It’s awful hard to take a whole lot of money from a group you know has a particular position then you conclude they’re wrong [and] vote no.” — Vice President Joe Biden in 2015.
“Lobbyists and career politicians today make up what I call the Washington Cartel. … [They] on a daily basis are conspiring against the American people. … [C]areer politicians’ ears and wallets are open to the highest bidder.” — Sen. Ted Cruz, R-Texas, in 2015.
“When some think tank comes up with the legislation and tells you not to fool with it, why are you even a legislator anymore? You just sit there and take votes and you’re kind of a feudal serf for folks with a lot of money.” — Dale Schultz, 32-year Republican state legislator in Wisconsin and former state Senate Majority Leader
“The alliance of money and the interests that it represents, the access that it affords to those who have it at the expense of those who don’t, the agenda that it changes or sets by virtue of its power is steadily silencing the voice of the vast majority of Americans … The truth requires that we call the corrosion of money in politics what it is – it is a form of corruption and it muzzles more Americans than it empowers, and it is an imbalance that the world has taught us can only sow the seeds of unrest.” – Secretary of State John Kerry, in 2013 farewell speech to the Senate
“American democracy has been hacked. … The United States Congress … is now incapable of passing laws without permission from the corporate lobbies and other special interests that control their campaign finances.” — Al Gore, former vice president, in his 2013 book The Future
“I think it is because of the corrupt paradigm that has become Washington, D.C., whereby votes continually are bought rather than representatives voting the will of their constituents. … That’s the voice that’s been missing at the table in Washington, D.C. — the people’s voice has been missing.” — Michele Bachmann, four-term Republican congresswoman from Minnesota and founder of the House Tea Party Caucus, in 2011
