The poll matches the last poll from Marquette, which also had Biden up by 3 points in Wisconsin.
Point: One of the big questions which arises when we look at the national polls results is whether or not hey’re an accurate representation of what is going on at the state level. One of the easiest ways to check is to compare state poll results to the past presidential vote in a given state. I did so for all telephone polls that called cell phones since the beginning of April.
When we average out these state polls, they suggest that Biden’s running about 6 points ahead of Hillary Clinton’s final margin.
In other words , the state polls suggest that Biden has a lead on national level around 8 points.
