Author's Notes: As I indicated on last Sunday's post, any discussion of the 2020 elections below will not have any speculation of how SCOTUS Justice Ruth Bader Ginsberg's death will impact the following elections, both out of respect for the late Supreme Court justice and because current conditions are changing significantly. It seems likely that such conditions may change even more now that President Trump has named his nominee and it seems likely that the formal confirmation process will begin.
Tonight's post was posted at 8:40pm PST (8pm normally) because I needed additional time to add last-minute information that I felt would benefit this post. This change is temporary, as I will continue to upload at 8pm PST from now on unless otherwise noted.
(and yes, I know that technically, I explore 13 races in total, but I got the title's number because I combined two races into one discussion for having a similar theme).
11/29/2020 UPDATE: While making the post-election analysis talking about the election results from the bellwethers listed below, I found a typographical error I made with one of the districts. The paragraph where I was talking about "Colorado's 5th district" is actually in reference to Colorado's 3rd district.
