Final answer:
The Supreme Court's alignment with protecting campaign spending as a form of free speech represents judicial conservatism, maintaining strict adherence to the Constitution's original intent, particularly the First Amendment.
Step-by-step explanation:
In several campaign finance reform cases, such as McCutcheon v. Federal Election Commission, the Supreme Court struck down elements that attempted to limit campaign spending, equating campaign spending to a form of political speech protected by the First Amendment. Considering this perspective and judicial decisions like Buckley v. Valeo and Citizens United v. Federal Election Commission, which judicial philosophy best describes the justices' decision making? The description aligns most closely with judicial conservatism, as this outlook generally emphasizes strict adherence to the original meaning of the Constitution and tends to protect free speech rights, including those expressed through campaign contributions and expenditures.
The justification for striking down campaign spending limits is centered on the protection of freedom of speech, rooted in the First Amendment. This has been seen in rulings like Buckley v. Valeo, where spending money was deemed a form of constitutionally protected speech, and Citizens United, where corporate spending limits were removed on the same grounds.
