The Supreme Court's decision on campaign finance has jumbled a seemingly simple rule of American politics — foreigners should play no role in U.S. elections. Now that the court has declared that corporations have a constitutional right to spend from their general treasuries to support or oppose candidates for president and Congress, the prospect of foreign influence in campaigns has emerged as a flashpoint in the back-and-forth between critics of the ruling and its defenders.

The justices also struck down part of the landmark McCain-Feingold campaign finance bill that barred union- and corporate-paid issue ads in the closing days of election campaigns.
