Polling errors could sway Trump or Harris to a landslide victory

Former President Donald Trump and Vice President Kamala Harris are in a tight race for the presidency, with polls showing them nearly tied nationally and in key battleground states. This close competition raises the possibility of a significant win for either candidate if polling errors occur. Pollsters are adjusting their methods to address past inaccuracies, particularly from the 2016 and 2020 elections. They are using a mix of polling techniques and statistical adjustments to better represent voter demographics. Despite improvements, polling can still be unreliable. In 2020, 93% of national polls overestimated Joe Biden's support. However, some past elections, like 2008 and the 2022 midterms, showed more accurate polling results.
