The US presidential candidates, Democrat Joe Biden and Republican Donald Trump, continued their campaign to question each other and pile up with accusations two days before the polls.

As Biden leads the polls, Trump is betting on swing states to win the race to the White House.

US President Donald Trump has commented that his rival Biden has canceled a campaign event in Texas after "harassment" from Trump supporters.

Trump shared a video clip in a tweet surrounding his supporters on a pro-Biden bus, and wrote, "I love Texas."

For his part, Biden said in a tweet that the United States could not bear another 4 years for Trump.

Biden added that about 23 million Americans are unemployed, and one company among 5 small companies has closed its doors, and that millions are at risk of being fired.

Trump had demanded at an election rally in Pennsylvania yesterday, to announce the election results at the end of voting day and counting the votes on Tuesday night, hinting at the possibility of tampering with ballot papers.

He said that the Americans need to know who won the elections soon after they are over and not after days or weeks, warning that the approval of the Supreme Court to extend voting by mail would open the door to tampering with ballot papers.

Trump's statements - which include doubts about the election results - come at a time when the US Department of Homeland Security announced that it had made preparations to protect federal buildings in Washington, in anticipation of unrest during the elections.

Polls

With only two days left before the polls, Biden maintains a strong lead nationwide, according to opinion polls.

Biden is ahead of Trump by 51%, compared to 43% in the latest Reuters / Ipsos poll conducted on the 27th and 29th of last month.

But Trump remains close to Biden in the crucial states to give him the 270 electoral college votes needed to win a second term.

Polls conducted by Reuters / Ipsos show the race remains unresolved in Florida, North Carolina and Arizona.

Trump's decline in opinion polls is partly due to the erosion of support from two major components of his voter base that gave him victory in 2016, namely whites without a college degree and the elderly, as well as the citizens ’rejection of his handling of the Corona pandemic, which has become the dominant issue in the race.

In the last two days of the campaign, the Republican candidate will hold 10 rallies, at a rate of 5 gatherings every day, and in the remaining two days he will visit Michigan, Iowa, North Carolina, Georgia and Florida.

With the election campaign reaching its final turning point, the US Elections Project platform reported that a record 90 million Americans had voted early in the presidential election.
