Final answer:
The phrase "We the People" in the Preamble to the Constitution represents the idea of popular sovereignty and the authority of the government based on the consent of the governed. The need for the 14th Amendment is explained by its clause expanding rights and protections to all citizens. The 19th Amendment granted women the right to vote.
Step-by-step explanation:
The phrase "We the People" in the Preamble to the Constitution means that the government's power comes from the people. It represents the idea of popular sovereignty, which means that the authority of the government is based on the consent of the governed. The phrase does not specifically mean only legal citizens but includes all people living in the United States.
The need for the 14th Amendment is explained by the clause in the amendment that states, "No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States." This clause expanded the rights and protections of all citizens, regardless of their race or ethnicity.
The need for the 19th Amendment is not directly related to the phrase "We the People." The 19th Amendment granted women the right to vote, ensuring that all citizens, regardless of their gender, had equal access to participate in the democratic process.
