Seems like it would be a lot more efficient to just blow in a bunch of outside air when its cool outside.

  Depends on if temperatures drop below 70 outside. If you're near the coast, open all windows at night when temps are low, and let the house get as cold as possible during the night. In the morning, close all windows and cover them with blinds, and turn the A/C off during the hottest part of the day. Don't open the fridge or freezer if possible, and keep lights off.

  Both, really. Normalize first with the ambient temperature and then run the AC to sub ambient down towards the 60s. AC efficiency increases as temperature decreases. You would have to deal with the fact that your house is now frigidly cold. Also, I can’t remember the last house I lived in California that had decent insulation - so that’s a major assumption.
