As a door knocker 1964-2013 I was told many times that door knocking was obsolete, But in 1964 the inner city Chicago I and other door knockers worked double Ikes vote in 1956 and tripled Nion’s vote in 1960.
In the 2000s the ground game registered voters and 100% of the new voters (with the exception of 2 Lizzies) voted Republican is a 3 way between Establishment and Conservative Republicans and Teachers Union Democrats. Most of the new voters were anchor baby citizens and a few naturalized. They voted 100% R. All Latinos voted 100% R (except 1 PR on welfare).
Alan Keyes types took over the ground game and got 100% of the Black vote, 100% of the Hispanic vote, 87% of the total vote in a heavily Heavily Hispanic 8 precints. (Only 87% because they did not get all the Hangover whhite divorcees and the guys shacking up with them.)
A winning strategy consists of all 11 players on the field, and a full Offense, a full defense, a full special teams. Vulnerable in any area and we lose, The wide receiver does not act like the guard or tackle. He shouldn’t. But they are both neeeded or we lose,
Point taken.
Knocking on doors is how AOC got elected.
