American elections, because of their absurd length, tend to focus a lot on various statistics in order to gauge the changing political fortunes of the candidates. But while each measure provides some indication of how things are going, one needs to treat each with some caution.
Opinion polls: These are probably the best measure of where the race stands but there are important caveats. The weird electoral college system in the US tends to have a bias towards red states so national polls have to be treated with caution. There are roughly seven so-called swing states (Michigan, Pennsylvania, Wisconsin, Arizona, Nevada, Georgia, and North Carolina) that usually determine the outcome of the election. Polls taken in just those states have more significance than national polls. This does not mean that national polls are useless but it is estimated that Democrats need approximately a +4% margin in the national polls in order to have an even chance of winning the Electoral College.
Right now, it looks like Democrats are approaching that 4% margin, making the race even, which is a huge improvement from the situation just a month ago.
A fresh Reuters/Ipsos poll released on Thursday showed Harris leading Trump nationwide by 45% to 41% – a margin consistent with other surveys since last week’s boisterous Democratic national convention in Chicago that confirmed the US vice-president’s status as the nominee.
…A Fox News poll on Thursday showed the vice-president with narrow leads in three out of four southern Sun belt states; 48 to 47% in Arizona, and 48 to 46% in both Georgia and Nevada. In the fourth, North Carolina – which Trump won by just 1.4% in 2020 – the Republican nominee was ahead by a single point, 48 to 47%.
The poll represented a big jump on recent numbers recorded by Biden, who trailed Trump by six points in Georgia in April and by five points in Nevada and Arizona as late as June.
