Joe Biden pips Donald Trump in Pennsylvania, Wisconsin opinion polls

Democratic presidential candidate Joe Biden appeared to lead President Donald Trump in Wisconsin and Pennsylvania less than a month before the Nov. 3 election, according to Reuters/Ipsos opinion polls released on Monday.

The polls showed the former vice president ahead by 5 percentage points in Pennsylvania, matching the poll's credibility interval. Biden led Trump by 6 points in Wisconsin. In both states, Biden improved his position relative to mid-September.

Reuters/Ipsos is polling likely voters in six states - Wisconsin, Pennsylvania, Michigan, North Carolina, Florida and Arizona - that will play critical roles in deciding whether Trump wins a second term in office or if Biden ousts him in the November election.
