If Mastriano doesn't book air time soon, there very well could be none left for him. TV ad space is not limitless and candidates in the past all over the country have learned this the hard way.
What do you think about the point that GOP operatives have reportedly seen internals showing Shapiro up by as much as a dozen points? Is the RGA thinking of triaging it?
Republican pollsters (and public pollsters) have been very slow to implement the same adjustments that Democratic pollsters have to counter non-response bias among non-college voters (of all races) and overrepresentation of the highly engaged among both party bases. I'm not surprised to hear that Republican internals are showing massive Democratic advantages in the rust belt (where the non-response bias issue is by far the most problematic) and if they cut Mastriano off because of it, music to my ears.
Why have they been slower to adjust? Issues with reaching enough non college voters to weigh properly?
