You could get better increased voter participation rates than the lauded Obama GOTV machine by dropping of early voter cards along with cofee and donuts at major employers and institutions.
You don't want general better voter participation. You want increased participation from people who are sure to vote for you.
The lauded Obama GOTV machine could have gotten better general participation rates by taking some of their billion dollars and expanding into red districts. They didn't because they were trying to win, not increase general participation. On the other hand, they did focus on institutions like colleges because those people vote Democratic.
Obviously it's targeted. Putting this program in place in most US cities would ensure a democratic president in perpetuity unless the other side wised up and started "expanding" it to the rest of the country, and it would still be incredibly painful due to increased logistical burdens.
If you make voting part of someone's routine, that's what it will become.
EDIT: In case it was unclear "Major employers and institutions" means cities.
