Chief Justice Ruth Bader Ginsburg:

If there was one decision I would overrule, it would be Citizens United.

I think the notion that we have all the democracy that money can buy strays … far from what our democracy is supposed to be. …

Citizens United was a terrible ruling. Most people asked to think about the issue for 10 seconds conclude that it’s a bad idea.

An ABC–Washington Post poll conducted February 4–8, 2010, showed that 80% of those surveyed opposed (and 65% strongly opposed) the Citizens United ruling, which the poll described as saying “corporations and unions can spend as much money as they want to help political candidates win elections“.

So why do so many politicians, especially Republicans, support Citizens United?

Because they can only get elected with money handed them by corporate lobbyists.

I don’t see how U.S. politicians can get out of this trap. They must sell their souls to corporations in order to get elected. 😦
