Each major-party candidate's campaign spent $1 billion and there were also over $1 billion spent by outsiders to the campaigns. But I'm looking at the bright side, which is hinted at by the headline for the NYT article on the subject: "Little to Show for Cash Flood by Big Donors."
So much money is spent that no one is big enough to be big. Everyone — all the way up to Sheldon Adelson, who dumped $300 million into the ocean of money — is diluted into smallness.
More speech is the classic remedy for whatever is considered the bad speech in the marketplace of ideas. Think about whether more money can work as the remedy for whatever you're thinking is the bad money in campaign finance.
