who gives money to political parties to raise money for the campaign?

bk: who gives money to political parties to raise money for the campaign?
I am just curious to know, who gives so much money for campaigning? According to Sheila Krumholz, the executive director of the Center for Responsive Politics, the presidential candidates alone have already raised more than $ 1.5 billion since the election cycle started in January 2007. Is that a joke? I know that to show ads on TV, they need some money but 1.5 BILLION is way too much.

Yeah…lots of people campaign on a platform of campaign reform, but somehow…they always tend to forget about reform once elected.

Money comes from Corporations and special interests, but alot of it is also individual donations.

Obama actually sells his campaign signs and banners to supporters instead of giving them freebies, so that’s a new way to raise money.
