Poll data of 2020 US presidential election

According to the Electoral College system, the president of the United States is elected by the electoral college, not directly by the voters. The number of electoral college members in each state, that is, the number of elector, is equal to the number of federal government members in each state. Together with three electoral votes from Washington, D.C., there are 538 votes nationwide. When a candidate wins 270 or more votes, the victory can be sealed.

The elected electors swear to vote for the winning presidential candidate in the state when voting in the electoral college, so the election results can usually be calculated according to the election results of each state on the polling day.

When voting in each state, the "winner-take-all" rule is implemented in most regions, and the presidential candidate who wins the majority of voters in the state will get all the electoral votes in the state.

Maine and Nebraska allow electoral votes to be divided. In Maine, the winner of the state won two of the four votes, and the other two votes fell into the pockets of the election winner in the House of Representatives constituency. Similarly, the winner of Nebraska won two of the five votes, and the other three votes were won by the winners of each house of representatives constituency.

California has the most electoral votes, up to 55, Texas has 38, New York has 29, while Delaware, Wyoming and Alaska have only three each.

In the American election, sometimes the location of the votes is more important than the number of votes. The voting results in most states are always consistent. For example, New York and California are loyal supporters of the Democratic Party, while Kentucky and Tennessee are safe voting warehouses for the Republican Party. Florida, Pennsylvania, North Carolina, Arizona and other swing states full of uncertainties are the main battlefields that determine whether a candidate can be finally elected.

In the latest poll results, Arizona’s 11 votes, North Carolina’s 15 votes and Maine’s 4 votes are more inclined to Democratic candidate Biden, Georgia’s 16 votes are slightly inclined to Trump, and Florida’s two candidates’ polls are less than one percentage point, and it is still unclear who will end up spending.
