text: The presidental candidate has to have trans-reginal appeal because a candidate with reginal appeal is unlikely to win. If a candidate were to campaign heavily in one region he or she will gain no electoral votes. so the candidates have to go croos contry and not stick to one region to actuly gain anything. A candidate can make every person in one reginon vote for him. But the candidate that go cross contry have a better chanse of wining because they have more electoral votes.
