Trump's victory over Harris: How was the race called so fast?

Contributing sentiments towards policy:

57% : Shortly after 10 p.m., it also became clear that Trump was holding his own with affluent suburban areas such as Waukesha County, Wis., and that Harris was running behind Biden's 2020 performance in major Democratic vote engines, including the college towns of Dane County, Wis., and Washtenaw County, Mich.Beyond the nature of the results, Stewart said election officials had improved some administrative challenges from 2020.
54% : A related reason for the earlier call this year compared with 2020 is "the fact that this was a 'uniform swing' election," said Charles Stewart III, director of the Massachusetts Institute of Technology's Election Data and Science Lab.Trump "performed around 2.5 to 3 points better in 2024 than in 2020 just about everywhere at the state and local levels," Stewart said.
48% : Second, the fact that the networks and the data providers knew it was a uniform swing election probably emboldened them to declare states for Trump earlier than if there was more variability in changes from 2020.
