I think the numbers are opposite for election day voters. I think it's like 2/3s of voters on election day will be Republicans.
In previous elections. I'm not convinced it will be the same this year. And biden has $400M in cash and he'll be able to explicitly target people
who haven't voted yet. The enthusiasm to get trump out of office is just too high. Republicans come out on Election Day but I think this massive lead + dems still coming out on election day will make this lead insurmountable
