美 대선 유권자 지지율...인종, 성별, 연령 별 차이는?

With less than 30 hours left until Americans head to the polls to decide who will lead their country for the next four years, most polls show Donald Trump's Democratic challenger, Joe Biden, holding a significant lead.
When we look at past elections, America's demographics have been a major factor in predicting the outcome.
What about this year? Will it will it not help us predict the outcome?
Our Choi Won-jong breaks it down.
With less than 48 hours left, Democratic presidential nominee Joe Biden still has a significant lead of 7-point-2 points over President Trump in Monday's poll of polls by RealClearPolitics.
And in the campaign so far, surveys have suggested that demographic trends this year are similar to those in 2016.
A month ago, Pew Research Center surveyed registered voters and broke down the reults by gender, race, age and education.
It found that as in 2016, women voters continue to favor the Democratic candidate, this year by 17 points more than the Republican.
The gap is narrower among men, Biden getting a lead of only 4 points.
In terms of race and ethnicity, President Trump is ahead among white voters by 7 points, though Biden has the overwhelming support of black voters by almost 10 to 1.
A political scholar here in Korea notes that African Americans have long tended to vote Democratic.
"African Americans do look at Democratic platforms that are found to be more attractive notably on healthcare. It's probably also the case for taxes as well."
And Joe Biden, he says, will definitely need the support of black voters to win this race.
"Getting the African American vote out is going to be very important for Biden to win. He is going to need the urban areas in order to overcome his significant deficit in rural areas."
Although Trump is faring slightly better among white voters in the race, the poll shows that white voters with college degrees tend to prefer Biden.
In terms of age, voters under 50 are by far more supportive of Biden, but older than that, they're split almost evenly.
As Professor Richey says, however, these trends might not hold up on Election Day.
"I think that part of that is maybe some ambiguity with the polling. I think the part of that has to do with what we refer to the shy Trump voters. Some older people might not feel comfortable responding to polling agents positively about their intentions."
Another issue is that most demographic surveys are based on registered voters rather than likely voters because that makes it easier to isolate the patterns.
Demographics can give us clues to what will happen on Election Day, but the actual result will depend on who turns up to vote.
