The Supreme Court’s current composition is such that the conservative majority would stay regardless of who wins the election, according to many experts. It’s important to note that terms of Supreme Court justices are for life, which means that their seats only become vacant when they choose to retire, pass away or are impeached.
Currently, there are six conservative justices and three liberal justices in the Supreme Court. Majority decisions and important rulings are significantly influenced by this balance. Even if the president elected is aligned more to the left and appoints a new judge during their term, it would not immediately change the overall conservative tilt of the Court.
The ideological balance of the Supreme Court is seen as vital because it has a huge influence on major legal decisions that can shape the policy landscape of the United States for years, or even decades. Consequently, the future appointments to the Court are often a significant issue during presidential campaigns.
