National polls only predict the popular vote due to America’s electoral college system, which awards the presidency to a candidate with 270 or more electoral votes, which are distributed to states based on the number of senators and representatives, not the total number of votes cast across the country. On the other hand, national polls can help anticipate trends in state polls.
