Opinion polls in the United States continue to point to a national leadership for Joe Biden.
But they also show that it is very even in several states and it is therefore difficult to draw any conclusions from the national figures.
- I'm looking at these false opinion polls.
We will win in any case, said US President Donald Trump when he spoke in front of a crowd at Monday's first stop, Fayetteville in the state of North Carolina.
"Enough of the chaos"
During the campaign sprint, Donald Trump is chasing voter support with a hectic travel schedule.
On Sunday, he visited Florida, Georgia, Iowa, Michigan and North Carolina.
The latter two he also visits on Monday, plus that Trump then also goes to Pennsylvania and Wisconsin.
Biden has chosen a slower pace and speaks on Monday in Pennsylvania and Ohio.
- We've had enough of the chaos.
We are done with tweets, with anger and hatred, with failures and irresponsibility, he thundered in his first election speech on Monday, in Ohio.
Land on full swing
It is a United States in full swing that goes to the polls and the risk of unrest is palpable.
In many holes in the country, shopkeepers have barricaded the shop windows with plywood boards.
- The Americans expect chaos, says SVT's foreign reporter Carina Bergfeldt on location in Washington.
The fact that many important states seem to stand and weigh also increases the risk of a chaotic aftermath.
- In Pennsylvania, it is already said that lawyers are the big winners.
Both Biden's and Trump's teams have hired a large number of lawyers who are preparing to question and quarrel about the votes in these important states, says Carina Bergfeldt.
The postal votes can be questioned
In addition, the record number of postal votes has been the subject of controversy.
President Trump has on several occasions criticized the system for being insecure and hinted that postal votes could be used for election fraud.
- This has become a hot potato in the US and it is a strongly party-polarizing issue, says political scientist Henrik Ekengren Oscarsson and points out at the same time that previous studies show that cheating with early voting systems has barely existed historically.
In this year's election, as many as two out of three votes may be cast prematurely.
- There is a clear majority who have a belief that this system works so there is still a legitimacy, says Ekengren Oscarsson.
