The United States of America is a Republic, which means, that the people elect representatives to speak on their behalf. One of the fundamental rights of an American citizen is the right to vote. This right should not be taken away from any law abiding citizen. The people were at the polling station and were trying to use their right to vote. They should never be turned away.
Those waiting in line to vote at the set closing time should not be turned away. This is because the delay might have been caused by the officers in the inside due to slow voting process. Therefore everyone should be given time to vote since it is their right. The other reason is that this people waited in the line for sometime and wasted their precious time.
Donald Trump does not care about democracy; he only cares about gaining power for himself. In a democracy, all citizens are guaranteed the right to vote. If someone arrives at a polling location before it closes, they should be allowed to vote. If Trump is against that, he is against democracy, and he has no business being president.
If people are waiting in line, they should be allowed to vote. The polls have always remained open. People cannot successfully predict how long it will take the line to move, and it is unfair to them to be turned away if they made the effort to come out and vote.
