@traders I will look into this and resolve tomorrow so please provide feedback in the next 15 hours

@traders The 538 polling average went from Trump +0.2 on June 27th (polling average pre-debate) to Trump +2.4 on July 7th (10 days after the debate).

I wrote "538’s polling average among polls conducted in 10 days after the debate". 538 appears to average across 14 days, so I cannot pull out the last 10 days easily. However, I think this issue is unlikely to influence how I resolve. If I could eliminate the June 24th-27th data from the 538 model, I think Trump's post-debate bump would be slightly higher but still between 2-5 pps.

Therefore, I am planning on resolving "2-5 pp shift toward Trump".
