Answer:
The answer is option C "They have lower voter turnout than presidential elections"
Explanation:
Elections for government federal offices are held in the US twice a year. Since the president of the US is chosen for a long term period, one of these election will happen in the President's long term of office. It is these decisions that are known as "midterm elections."During a midterm political race all the 435 individuals from the Place of Agents are on the ballot and 33% or at least 30 of the 100 individuals from the Senate.
The explanation as to just a single third of the Senate is on the ballot is that Representatives serve long terms of office and the writers of the Constitution needed to guarantee that they were not all moved out at one time.
The Voting Rights Act of 1965, signed into law by President Lyndon B. Johnson, aimed to overcome legal barriers at the state and local levels that prevented African Americans from exercising their right to vote as guaranteed under the 15th Amendment to the U.S. Constitution.
