I’m seeing a LOT of very slick and well produced Biden ads. Not much in the way of Trump ads.
It varies based on where you live. They’re going to spend the money where it’s going to do the most good. If the polls where you live show either the state is solidly in the Republican camp OR that there’s no way that it would ever go Republican, you’re not going to see money wasted on ads through local media.
A ‘battleground’ state will see a TON of ads from both sides.
The goal is to get enough electoral college votes, not popular votes. If a state is going to go red, then it doesn’t matter if you got 50,000 extra votes from that state or 100,000 extra votes. You don’t get any more electoral college votes by winning a state with a bigger margin.
