What it shifts is advertising from expensive media markets with small geographical boundaries (NY, LA) to less expensive ones that have large boundaries (Kansas City, Raleigh.) It works out that, because of the large boundaries, the cost to reach each consumer is far lower.

Moreover, I'd wager that the stumps that stump speeches occur on will go to more places with more concentrated populations - there are more butts within n square miles to put in seats, as well as the most-watched news media.

My opinion is that both outcomes are preferable to stumps AND media going to half a dozen battleground states.
