Sorry for a stupid, sort of related question.
From what I understand the presidential election is in 2 parts the popular vote and the electoral vote.
The popular vote chooses the 538 electors and they in turn vote for the president and vice president.
The electors are split into either the Senate (100 - 2 per state) or the House of Representatives (438 varies by state).
In the popular vote, do you know whether the candidate(s) you vote for are standing for the Senate or the House of Representatives or not? How is that decision made? Whether en elector will sit in the Senate or House of Representatives.
