This document summarizes campaign financing trends in the 2012 US presidential election. It notes that the 2008 election set fundraising records at $6 billion total. President Obama raised over $6.5 million for his 2008 campaign, with $6 million coming from donations less than $100. The document attributes Obama's fundraising success to his innovative use of social media and the internet to engage supporters and micro-donors. However, it also notes that the rise of Super PACs in 2012 likely reset campaign financing, with more money coming from large donations to outside groups rather than small donors.
