The correct answer is D) They questioned President Carter’s leadership.
Many Americans seek a change in the presidential election of 1980 because they questioned President Carter’s leadership.
Most Americans disapproved the way President Jimmy Carted had handled many internal and external issues. In the 1980 US elections, Democratic candidate Jimmy Carter aspired his reelection but he was defeated by Republican candidate Ronald Regan. He won the electoral vote 489-49. The Democratic Party suffered a considerable division before the elections when Senator Tedd Kennedy aspired to be the official candidate instead of Carter.
In my opinion it is a positive development that the vice president's resppnsibilities have increased. The reason is that in this way the vice president can demonstrate and prove that he is able to be in charge of the government in case anything happened to the president.
