Answer:
the probability is remote for all americans
Step-by-step explanation:
The closest elections that have happened in the history of the United States have have a difference of .2% in the popular vote, some of them have even lost the popular vote and still won the election, for example Gore vs Bush in 2004 where gore gained 500,000 more votes than bush in the popular vote but still lost the electoral vote, so the reality is that there is a remote probability for all americans to tip the balance of an election to decide the winner.
