In the 2020 elections, the vast majority of Black voters who supported Biden backed Trump.

Former President Donald Trump has significantly increased his support among African American voters in Wisconsin, a key part of the Democrats' 'Blue Wall.'

According to NBC's exit polls, Trump received support from about 20% of Black voters. This rate is more than double the 8% support he received in 2020. With pre-election polls also encouraging, Trump is making a significant effort to secure minority votes.

At the same time, according to exit polls, he received support from 38% of Hispanic/Latino voters. This group had supported Biden by a margin of 23 points in 2020, with a vote of 59% to 36%.

Trump is also seeing an increase among Latino male voters in 10 key states. This group supported Harris by a good margin of 54% to 44%, but this may not be the rate Harris needs in the large electoral districts where they make up a significant portion of the Democratic coalition.

Throughout his campaign, Trump has claimed that illegal immigrants are "taking jobs from Blacks and Hispanics" and promised to increase production in the U.S. by imposing tariffs on imports.

In Michigan, where the minority population is higher, Trump received only 9% of the Black vote according to exit polls.

According to Pew Research, there are 34 million Black voters eligible to vote in the U.S. This number has increased by 7% compared to the 2020 elections and constitutes 14% of the total voter population.

Black voters are a critical part of the Democratic coalition that enabled Barack Obama to become the first Black president.

If Harris becomes president, she will be the first Black woman president. Trump brought the issue into the campaign by questioning Harris's ethnicity during a controversial interview with Black journalists in Chicago.

Although Harris has strong support among Black voters, it remains to be seen whether she can maintain the margin Biden achieved on Tuesday.
