The 2016 Campaign Fundraising Landscape

At this early point in the 2016 presidential campaign cycle (with only one declared major candidate so far), a lot of money is already being raised in a variety of ways by those who are considering running for president. This is an early primer for 2016 campaign fundraising: what organizations exist, where they can raise their money, where they can spend it, what they legally must disclose, and which entities have been chosen by the possible 2016 presidential candidates (most of whom will stress that they are not candidates ... yet).
