What about physically sending people to battleground states? Unless they are quietly selected for their utter diplomacy and charm, I wonder about that one too.
Good suggestions. You sound like a pro.

Not cost effective unless you live right next to a population center across the border in a battleground state. Here in CA, I'd have drive to Nevada--probably two tanks of gas. Better use of my resources to donate the gas money to a conservative candidate in a close race.
