Imagine a political figure is elected by popular vote of an entire state. This figure represents the state in a federal legislature. What position does this person hold?

Answer 1

The political figure you are describing holds the position of a U.S. Senator if they represent the state in the United States Senate, or they hold the position of a U.S. Representative if they represent the state in the House of Representatives. Senators are elected by the popular vote of the entire state for a six-year term, whereas Representatives are elected to represent specific congressional districts within the state for a two-year term.
