More than 1.4 million have already voted in the presidential election, as battleground state polls show no clear frontrunner
More than 1.4 million people have now voted in the presidential election, as Kamala Harris and Donald Trump continue to crisscross the country in the final stretch of a neck-and-neck campaign.
Their vice-presidential picks, JD Vance and Tim Walz, also faced off this week in the only vice-presidential debate of this cycle. But initial polls suggested voters saw the debate as a draw, without clear impact on the race.
Harris earned her highest national polling average since July, though the presidential race remains extremely close in battleground states, according to the Guardian’s poll tracker. Harris is leading in five of seven swing states, according to the Guardian’s average of high-quality state polls aggregated by the polling analysis platform 538 over the last 10 days. But overall, both candidates continue to have about even odds of winning.

They do use weights and adjustments to deal with this. I don’t know about US polling but in the UK there is a shy conservative factor. People don’t like to say or admit they are conservative, so the polls factor this in. They also factor who answers and responds and try to correct for it.
