Why are contributions tracked starting in Jan. 2007?

The graphic shows individual donations for the 2008 election cycle, a two-year time period that began on Jan. 1, 2007. For campaign finance purposes, the general election phase begins when the candidate formally accepts the party's nomination. (top of glossary)

What are total receipts?

This figure includes total contributions to presidential candidates at all contribution levels. The graphic, however, only shows detail for itemized contributions of $200 or more. (top of glossary)

Why aren't donations below $200 included?

The graphic shows detail for all individual or aggregate contributions of $200 or more. Campaigns are not required to provide details such as the donor's name, address and occupation for most contributions of less than $200 when reporting their finances to the Federal Election Commission, the independent regulatory agency responsible for the civil enforcement and administration of campaign finance laws. Presidential campaigns file monthly election year reports with the FEC. (top of glossary)

What are the contribution limits?

Under federal law, in 2007-08, an individual may contribute no more than:

• $2,300 to a candidate per election (primary and general)

• $28,500 to a political party per year

• $108,200 combined per election cycle to candidates, parties and PACs

(top of glossary)

How was the sector list established?

The Federal Election Commission does not require individual donors to indicate the sector or industry in which they work.

The Center for Responsive Politics (opensecrets.org) uses a hierarchical coding system to classify contributions by sector, industry and interest group.

The graphic shows 14 sectors — ten covering business groups and one each for "labor," "ideological/single-issues," "other," and "unknown." See the list below for the industries that make up each sector. Opensecrets.org has full detail on sectors, industries and categories.

In many cases, the sector and industry can not be determined from the information provided by the donor to the FEC. These contributions are not reflected in the sector portion of the graphic.
