What is a common platform shared by both major political parties in the U.S.?

Support for the military is a common platform shared by both major political parties in the U.S. This bipartisan agreement stems from the recognition of the military's crucial role in national defense, security, and foreign policy. Both parties acknowledge the importance of maintaining a strong military presence and providing adequate resources and support for service members and their families. This consensus can be seen in the way both parties often support funding for defense programs and initiatives to enhance national security.

The other options represent topics that may generate more division between the parties. For instance, free trade agreements have been a point of contention, especially regarding how they affect American jobs and industries. Universal basic income is a concept that finds more traction in progressive circles, mainly associated with the Democratic Party rather than a common stance with the Republican Party. Legalization of marijuana typically sees varying support levels within both parties, leading to differing opinions rather than a unified platform.
