Contention 1: Proper representation is lost.
When there is an election, the Electoral College does not give an accurate representation of the people because they vote for representatives, who in reality cast their votes. Not only that, but a candidate can win an election with just 270 electoral votes.
South Sea Republic Organization in 2008 explains:
“The Electoral College is an indirect voting mechanism. US citizens vote for representatives who then cast ballots for the US President. The electors do not have to cast their ballots as per the popular will in that state; they can defy the voters if necessary. This was done to protect against tyranny or a noble trying to usurp the democratic system. The convention however is that the electors vote in a block as per the citizen voters’ wishes.”
CNN explains:
In our current system, the president is elected by the Electoral College and not directly by the people. The number of electoral votes each state receives depends on its population and representatives are chosen to vote on behalf of the people in the state. To win, a candidate has to win 270 electoral votes, which is a majority. If neither candidate gets that, Congress determines who wins. A few times, the American people's choice for president hasn't actually been elected or represented. The new system would also nationalize the presidential campaign.
Contention 2: States are being excluded.
Right now, candidates spend most of their time campaigning in battleground states. They do not try to win over voters in small states, such as Ohio and New Hampshire.
Oxford University in October of 2011 furthers:
By itself, California now has fifty-four electoral votes, making it more valuable to a candidate than sixteen smaller states with three votes each. … Campaigns
