In Biden v. Missouri, the Supreme Court considered whether a state may require that presidential electors cast their votes for the candidate who won the popular vote in their state. The court held that states do not have this authority and cannot bind electors to any particular candidate or party. Instead, it is up to each elector to decide how they will cast their ballot when voting in the Electoral College. This decision reaffirms an individual's right to choose whom they support as president and ensures that all citizens are represented equally in our democracy regardless of which political party they belong to or what state they live in.

In Biden v. Missouri, the Supreme Court was asked to decide whether the Missouri Supreme Court had violated the First Amendment when it denied a petition for a writ of mandamus to compel the state to allow a referendum on a proposed constitutional amendment. The majority opinion held that the Missouri Supreme Court had not violated the First Amendment, and the petition was denied. Justice Breyer wrote a dissenting opinion, arguing that the majority opinion failed to recognize the importance of the First Amendment in protecting the right of citizens to petition their government for redress of grievances. He argued that the Missouri Supreme Court had violated the First Amendment by denying the petition without providing any explanation for its decision. He further argued that the majority opinion had failed to consider the fact that the proposed amendment was of great public importance and that the people of Missouri had a right to vote on it.
