Answer:
The basic principle of the Constitution that was reinforced as a result of the Civil Rights Act of 1964 is the principle of equal protection under the law.
The excerpt from the Civil Rights Act prohibits any person acting under color of law from applying different voting standards, practices, or procedures to individuals based on their race or other protected characteristics. This directly reinforces the principle of equal protection, which is enshrined in the 14th Amendment to the Constitution.
The 14th Amendment states that no state shall "deny to any person within its jurisdiction the equal protection of the laws." By prohibiting discriminatory voting practices, the Civil Rights Act of 1964 upheld this core constitutional guarantee of equal protection for all citizens, regardless of race or other protected traits.
Prior to the Civil Rights Act, many states had laws and practices that effectively disenfranchised African American and other minority voters, denying them the equal right to participate in the political process. The Civil Rights Act sought to remedy this violation of the equal protection principle by establishing uniform, non-discriminatory standards for voter qualification and participation.
So in summary, the Civil Rights Act of 1964 reinforced the fundamental constitutional principle of equal protection under the law, which is a bedrock guarantee of the 14th Amendment and a core tenet of American democracy.
