In 2008, about a fourth of all voters were contacted in some way by the Obama campaign. Mr. McCain’s campaign contacted 18 percent of general-election voters. A FiveThirtyEight study from just after the 2008 election found that “each marginal 10-point advantage in contact rate translated into a marginal 3-point gain in the popular vote in that state.”
So guys: If you care about winning this election and want to make sure the President we elected stays in office: you know what to do. Knocking on doors, making phone calls and registering voters TRANSLATES DIRECTLY INTO ELECTORAL MARGINS OF VICTORY.
