After 92 AD, the palace eunuchs increasingly involved themselves in court politics, engaging in violent power struggles between the various consort clans of the empresses and empress dowagers, causing the Han's ultimate downfall. Imperial authority was also seriously challenged by large Daoist religious societies which instigated the Yellow Turban Rebellion and the Five Pecks of Rice Rebellion. Following the death of Emperor Ling (r. 168189 AD), the palace eunuchs suffered wholesale massacre by military officers, allowing members of the aristocracy and military governors to become warlords and divide the empire. When Cao Pi, King of Wei, usurped the throne from Emperor Xian, the Han dynasty ceased to exist.

The 2004 election was the first to be affected by the campaign finance reforms mandated by the Bipartisan Campaign Reform Act of 2002 (also known as the McCainFeingold Bill for its sponsors in the United States Senate). Because of the Act's restrictions on candidates' and parties' fundraising, a large number of so-called 527 groups emerged. Named for a section of the Internal Revenue Code, these groups were able to raise large amounts of money for various political causes as long as they do not coordinate their activities with political campaigns. Examples of 527s include Swift Boat Veterans for Truth, MoveOn.org, the Media Fund, and America Coming Together. Many such groups were active throughout the campaign season. (There was some similar activity, although on a much lesser scale, during the 2000 campaign.)
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many campaign finance groups were there in 2000?
Ah, so.. unanswerable
