What problem with campaign financing did the passage of the mccain-feingold law in 2002 attempt to solve?

The primary goal of the McCain-Feingold Law was to stop the increasing use of "soft-money" (unregulated monetary donations) to fund advertising by political parties on behalf of their candidates. Corporations were allowed to donate large and unlimited amounts of money to state parties, under state rules, and that money could be funneled to candidates.
