Iran Press/ America: The Democratic candidate holds a significant lead in national polling, anywhere between four and 10 percentage points, according to a cluster of polls released on Monday.
But the Republican president is performing better in some of the battleground states he must win to secure a second term.
In Florida, the largest of the handful of crucial swing states, Biden leads by just 1.7 points, according to an average of leading polls.
Polls on Monday afternoon also had Biden very narrowly leading Trump in Florida and in a dead heat in North Carolina and Arizona.
On a national level, it gave Biden an outright majority among all likely voters: 52% to 44%.
