What Biden is doing quite well is if Trump has a couple of good days Biden steps in and stems the momentum. in 2016 Trump would put 2-3 weeks together where he would really close the gap. Currently he has a good couple of days, and then Biden steps in and stems the momentum. Its happened 3 times already.
August 3-5th Trump closed the gap from an 8.3 to a 7.6.Biden stepped in, a week later it was back to an 8.3 and 3 weeks later it peaked at a 9.3. Then between August 25th-31st Trump cut the gap again, from a 9.3 to a 7.1 but again today Biden has stepped in and is now at a 7.4 and it again looks to be steadying again. You see similar in late July, Trump cuts the lead over a couple of days from an 8.8 to a 7.7 and and over the next week Biden just eases is back to a 8.3 lead.
For context, in 2016 Trump over a 20 day period is able to take a 5.4 Clinton lead into a 0.6 lead. Or across August he clways back a 7.5 deficit to a 2.5 deficit over the course of around 40 days.
I mean whether it's Biden, Trump, the campaigns, the onbective situation on the ground- Trump just can't get the sort of sustained momentum that he had in 2016 as yet. He has 1-5 good days and then Biden tends to jut steady the momentum over a 7-20 days period.
In 2016, is he polling around 3.5-4 behind and ends up being predicted to lose by that amount from this point. So in essence he doesn't really squeeze much more on Clinton here on in. In 2016 he hada good September, but Clinton had a good October. You can never fully predict such a race, but if Biden weathers this post conference boost for Trump and keeps the gap at +8 Trump is beginning to need snookers (if the polls are accrurate).
The other interesting take outs, are even though polls closed a bit post conference, Bidens reputation went up relative to Trumps. So the background numbers were ok for Biden. LIkewise, interestingly in Wisconsin, it bucks the trend and has actually swung towards Biden more, following the protests, which is a small sign that the Law and Order debate is probably not helping Trump.
