Place potatoes, salt, and garlic in a 4-quart pot with  enough water to cover the potatoes. Bring to a boil.  Reduce heat to medium and cook until potatoes are  fork tender, about 20 minutes.

Warm broth in a small saucepan over low heat.

Drain potatoes and place in a large bowl. Add broth  and margarine and mash with a potato masher, electric mixer, or ricer to desired consistency.
