On 21 July, Joe Biden dropped out of the presidential race and endorsed Kamala Harris. This historic move changed the landscape of the election and how many felt about the race. As the election enters its final weeks, Guardian US is averaging national polls to see how the two candidates are faring. We will update our averages once a week, or more if there is major news.
To calculate our averages, Guardian US took a combination of head-to-head and multi-candidate national polls and calculated a rolling 10-day average for each candidate. Our poll tracker uses polls gathered by FiveThirtyEight and filters out polls from lower-quality pollsters.
Polling averages capture how the race stands at a particular moment in time and are likely to change as the election gets closer. Our averages take into account national polls and are an estimate of the support that the candidates have on a national stage. The election is decided by the electoral college, so these averages should not be taken as a likelihood of winning the election in November.
