First step, check all fuses.
On some of these cars, the wire in the steering column would fray and short out, blowing a fuse.
Also, jumper power to the horn anyway, to see if it is working.

At the steering wheel, doesn't the horn switch just complete a ground circuit? As in there is never any power going through the horn switch at the steering wheel.

The horn wire in the column grounds the horn relay. The column must be grounded to the dash/body in order to complete the circuit.
The horn relay contacts do the heavy work of supplying current to the horn(s).
The column wire, if shorted would blow the horn and not blow a fuse. Shorted horns may blow a fuse.

From the 1970 Dart/Challenger service manual on MyMopar:
"The horn circuit consists of a horn switch located in the steering wheel hub and a horn relay mounted in the passenger compartment under the instrument panel at the left kickpad".
It would likely be a 3-terminal cube. You should hear or feel a faint click inside it when pressing the horn button.
The manual has the troubleshooting procedures and wiring diagrams.

Here is a link to a wiring schematic for your vehicle. Scroll until you find a reference for 1971 Dodge Dart. There are 2 schematics.

MyMopar - Mopar Forums & Information - Mopar Wiring Diagrams 1966 to 1971 (at http://www.mymopar.com/index.php?pid=27 )

In addition to the tips presented look at the wiring connector that carries the load side power from the horn relay to the horns. There is a connector at the firewall through which the load side power for the horn passes. This must be in good condition and not corroded and separated.
