President Donald Trump has suggested Democratic presidential candidate Joe Biden's poll numbers are plunging despite trackers showing his lead has dipped by less than a point over the last month.

Emboldened by one recent poll which gave him a lead, in the popular vote overall and in battlegrounds, the president hit out at Biden's numbers, suggesting his return to in-person campaigning is because they are plummeting.

 However, poll trackers from FiveThirtyEight and Real Clear Politics still put Biden ahead looking at the average of results from multiple surveys—despite some surveys having shown a slight tightening of the race.
