The last US Senate race in Pennsyl-tucky was in 2018, a midterm year, so it won't be an apples-to-oranges comparison.
Not a straight-up apples to apples, but we won't have the presidential race static in the data.
2018 was a dud race by both sides. Barletta who is who thr party wanted to be the candidate for Governor this time and lost to Mastriano. GoP establishment didn’t even take the field in 2018.
Will be interesting to see what the numbers show, but dynamics of the races are very different.
Believe about 10 Million spent to back Barletta in 18 and 20 Million to back Casey
2020 more than 100 million spent was spent by each side.
I am interested I. Your numbers but these races weren’t even close to apples to apples
