A Law Limiting Soft Money Political Contributions

A law limiting soft money political contributions

A) was upheld by the Supreme Court because political contributions are not a form of speech.
B) was upheld by the Supreme Court because it regulated only the source of money, not the amount that a candidate could spend.
C) was held unconstitutional by the Supreme Court because it interfered with a political candidate's right to campaign.
D) None of the above; the Court refused to rule on the issue holding that it was a political question.
