30. Which United States Supreme Court decision focused on how states count popular votes for president and vice-president?

Answer: A

Explanation:

Bush v. Gore (2000)

The Supreme Court decision in Bush v. Gore (2000) addressed the methods used by states to count popular votes in the presidential election, specifically focusing on the recount procedures in Florida. This landmark case ultimately determined the outcome of the 2000 presidential election.

A) Bush v. Gore (2000)

This option is correct as the case directly dealt with the counting of votes in Florida during the 2000 presidential election. The Court ruled that the differing standards of counting votes violated the Equal Protection Clause, highlighting the importance of uniformity in the electoral process.

B) U.S. v. Nixon (1974)

U.S. v. Nixon was primarily concerned with presidential privilege and the legality of withholding information during the Watergate scandal. It did not address issues related to the counting of popular votes or election procedures, making it irrelevant to the question.

C) Baker v. Carr (1962)

Baker v. Carr focused on the issue of legislative apportionment and the principle of "one person, one vote." While it addressed electoral fairness, it did not pertain specifically to the counting of popular votes for presidential elections, thus making it an incorrect choice.

D) Citizens United v. Federal Election Commission (2010)

Citizens United v. FEC dealt with campaign finance laws and the regulation of political spending by corporations and unions. This case does not relate to how states count popular votes in presidential elections, rendering it an incorrect option.

Conclusion

Bush v. Gore (2000) is definitively the correct answer as it directly involved the Supreme Court's intervention in the electoral process concerning vote counting. The other options, while significant in their own right, do not address the specific issue of how states count popular votes for president and vice-president, making them unsuitable responses to the question.
