What caused Trump's rise and Biden's dip in the polls the past 2 weeks? 1. On July 27th two weeks ago, Biden had an average 6.2 pt lead in the battleground states of WI, NC, FL, PA, MI, AZ. Today it is 4.9 pts. 
2. Trump's approval was 42.1 pts 2 weeks ago, now it is "up" to 43.1
3. In the head to head national polls, Biden's lead has went from 9.3 to 6.4 pts since July 27th. 

Is this just a blip in the data or is there some big changes going on in the race?
