是否可以允许公司、工会和非营利组织给政党捐赠？

In the 2010 Supreme Court case Citizens United vs FEC, court ruled that the free speech clause of the First Amendment prohibited the government from restricting independent expenditures for political campaigns by corporations, including nonprofit corporations, labor unions, and other associations. The court’s landmark decision overturned the Bipartisan Campaign Reform Act of 2002, also known as “McCain-Feingold.” That law had prohibited unregulated contributions to national political parties and limited the use of corporate and union money to fund advertisements discussing political issues within 60 days of a general election.
