Support for Republican-elect Donald Trump has increased significantly since he last ran for the US presidency.

In defeating Democrat Kamala Harris, Trump won a higher percentage of the vote in each of the 50 states and Washington, D.C., than he did four years ago.

He won more real votes than he did in 2020 in 40 states, according to an Associated Press analysis.

To be sure, one factor in her loss was Harris' decline of more than 7 million votes compared to President Joe Biden's 2020 total, especially in major cities with shifting states that were strongholds of the party that won the election.

But despite a lower national turnout than in the 2020 election, Trump received 2.5 million more votes than he did four years ago. He beat seven of the most competitive states. He won a convincing victory in the Electoral College, becoming the first Republican candidate in 20 years to win a majority of the popular vote.

 While Trump improved across the map, his gains were particularly notable in the urban counties that contain the cities of Detroit, Milwaukee, and Philadelphia, which were Harris' electoral drivers in the industrialized states of Michigan, Wisconsin, and Pennsylvania. Harris garnered more than 50,000 votes - and five percentage points less than Biden - in Wayne County, Michigan, which makes up the lion's share of the Detroit metro area. She was nearly 36,000 votes behind Biden in Philadelphia County, Pennsylvania, and about 1,000 votes less in Milwaukee County, Wisconsin.
