6. Based on the passage, what can be inferred about presidential election system in the US?

Question

Questions 6-10 are based on the following passage!

Eligible US voters on election day don't select the President directly. They are voting for 538 electors instead, who meet in their respective states and vote for President and Vice President. The number is 538 as there are 100 senators (2 per state) and 438 representatives (distributed by population). These electors comprise the Electoral College.

Each state, no matter how populous, gets at least three electors, and the remaining are in proportion to the population of the state. For example, California, the most populous state, has 53 congressmen and two senators, and gets 55 electoral votes. Meanwhile, a handful of sparsely populated states like Wyoming, Alaska and North Dakota (and Washington DC) have the minimum of three. In a sense, on election day voters are telling their states how they want it to use its electoral votes, and the electors vote for the president on behalf of the people in their state. Generally, states award all their electoral college votes to whoever won the poll of ordinary voters in the state.

To win the presidency, 270 electoral votes are needed to get a majority of the Electoral College. The number of electors cannot change without a constitutional amendment, but electors allocated to each state can change every 10 years. In the electoral college system, the candidate with the highest number of votes in a state claims all of the state's electoral votes. For example, Trump claimed all 29 electoral votes of Florida, winning the election over Clinton by a margin of 2.2 percent. By narrowly winning key battleground states, Trump surpassed the 270 Electoral College votes necessary to win the White House despite Hillary's victory over popular votes

Candidates can win the popular vote and lose the electoral college. Some called the electoral college a 'winner-takes-all' system, as small margins in the key state's with large populations (and thus more electors) can tilt the US elections in one party's favour. Key states, also known as swing states or battleground states or purple states, are highly competitive states that have historically swung between voting for different parties in presidential elections. The high-stakes game of winning over the swing states means candidates spend more budget and effort to win them.
