Yet as momentum for change has grown, so has big money's role in our elections. In the 2012 election — the most expensive in our history — a huge chunk of the money came from a tiny number of contributors. In fact, the top 32 donors to Super PACs in the 2012 election, giving an average of $9.9 million each, contributed as much as every small donor to Barack Obama and Mitt Romney combined. This means 32 people spent the same amount as 3.7 million Americans. In addition, election spending with undisclosed or partially disclosed sources grew from $94 million in 2008 to $620 million in 2012.
