Are the congressional seats in each state occupied by the same people selected to be the electors?

Answer 1

The short answer is, it depends on the state. And the question is really more like "do states select their state representatives and state senators as their electors?"

The long answer: "Electors earn their positions through complicated and often random processes that differ from state to state — and that’s the source of the unrest plaguing the Electoral College today.

Democratic and Republican state parties nominate their own slates of electors — some as early as the spring and others as late as October. In many states, elector candidates are picked at congressional district and state conventions, when local activists also pick their delegates to the national convention. Elector contests are usually afterthoughts compared with the more sought-after convention roles."
