Answer all questions following the passage on the basis of what is stated or implied in the passage.Congressman Hast
41、ings has proposed that Congress should abolish the Electoral College system for electing the president and replace it with a system of direct popular election. The Electoral College system is flawed, he argues, because it runs directly counter to the democratic principle that every citizens vote sho
42、uld count equally.Because of the winner-take-all system in which the candidate who receives the most popular votes in a state receives all of that states electoral votes, the citizens who voted for the losing candidate are effectively disenfranchised from the national election, even if their candida
43、te lost the state by only a handful of votes. Moreover, because each states number of electors is the same as its number of members of Congress, the citizens of small states get a disproportionately larger vote than citizens of more populous states. In the 1988 election, for example, the combined vo
44、ting-age population of the six least populous states-Alaska, Delaware, North Dakota, South Dakota, Vermont, and Wyoming-was 3,119,000. These six states held 21 electoral votes among them. Florida, with a voting-age population of 9,614,000, also had 21 electoral votes. Because of inequities of this n
45、ature, there have been four presidential elections in which the candidate who won the Electoral College actually lost the popular vote: 1824, 1876, 1888, and 2000.Congressman Markham has argued that Hastingss proposed changes are unnecessary and even dangerous. First of all, he argues, the Electoral
46、 College system, whatever its flaws, has resulted in a stable democratic government for more than 200 years, which shows that it is doing something right. Second, the winner-take-all system helps create decisive majorities in the Electoral College, thereby reducing the problem of disputed elections
47、that we might see in the event of direct popular elections. Third, the current system of allocating electors helps protect the interests of small states, which would be largely neglected in favor of large states if the Electoral College were based entirely on population. Protecting these states righ
48、ts is essential to upholding the principle of federalism (in which the states and the federal government maintain distinct powers).When the Electoral College system was first formalized by the Twelfth Amendment in 1804, a direct popular vote would have been impossible to implement, and the Electoral
49、 College was probably the best way to approximate the will of the people. Advances in technology and communication, however, now mean that a direct popular vote would be as simple, if not simpler, to administer than the current Electoral College system. Alternative ways to reform the system would be to do away with the winner-take-al
