But the latest poll shows the 13-point lead is now gone and President Trump is within the margin of error:

New @MonmouthPoll has race in PA tightening significantly — within margin of error.

Among registered voters:
Biden 49 %
Trump 45
(+/- 4.9)

Aug 28-31, 400 PA voters

Mid-July Biden had 53, Trump 40. Since then Trump has gained with men and younger voters.

So, was the July poll just really, really bad or the race has tightened this much?

Monmouth poll shows the race in Pennsylvania has tightened up by a net 9 percentage points

Today: Biden 49%, Trump 45% (MOE: 4.9%)

Biden leads under different scenarios, but these are also within the margin of error:

2/ Poll has 2 likely voter turnout models —

High turnout LV:
Biden 49
Trump 46

Low turnout LV:
Biden 48
Trump 47

Both within margin of error

And Joe Biden’s favorability isn’t that much better than the president’s:

3/ Biden favorable/unfavorable
48/46

Trump 44/51

45% of registered voters say Trump has done a good job handling coronavirus; 53% say he has done a bad job. https://t.co/TN0t9sgjzA
