I think the disadvantage here might be overstated a bit. Trump was outspent and had poor organization in the primary too, and he still won pretty easily. With name recognition as high as Trump and Hillary, I'm not sure how much people need to see ads to make their decisions. I'm not saying it won't matter, but I don't think it matters as much as people think it does.
I agree to an extent - But Trump held wide wide leads in the Republican primaries and underperformed his polling in nearly every state because of his significant disadvantages in organization and last minute voters turning away from him.
