The New York Times (and others) has been doing great work in using graphics to communicate data. Look at this: It shows each Senate race over time, who is leading and by how much.
When blue show the Demo is ahead and the height shows from a small lead to a huge one. In Kansas there is green color because the Democrat claims to be an independent. When the colors disappear there is a tie.
It’s fascinating to pick a race and follow it across.
Surprise. In Virginia the graph shows the Demo Warner always way ahead. On the morning after the gap is 2,500 votes in the large state.
Here is the link. I am also pasting a screen capture done the "morning after" of November 5.
