President Biden has cut into former President Trump's lead after his widely panned performance in the first debate.

Some post-debate polls had showed Trump widening his lead against Biden in key swing states.

A Bloomberg/Morning Consult poll out Saturday showed Biden only trailing Trump by 2 points, within the margin of error, in Arizona, Georgia, Nevada and North Carolina.

Biden is leading Trump in Michigan by 5 points and Wisconsin by 3 points while Trump is ahead by 7 points in Pennsylvania, according to the poll results.
