What is with the fascination and compulsion with some people who want to produce maps with a tied situation . . . ?
I don't know why others do this, but as for me . . .
On election night, I like to start with a projection of what I believe to be the most likely tie scenario. This places the candidates on an equal footing, and it's easy for me to see the impact of each call. If they come on at 6:00 and tell me Trump has won Indiana, I leave my projection at 269-269--but if they tell me Clinton has won Indiana, I change my projection to 280-258.
I like this better than looking at totals that are more about poll-closing times than anything else.
