text: Due to the even amount of votes in the electoral college, there is a slight chance of a tie. However, with all but two states being part of the "winner-take-all" system, the chance of that happening are astronomically low. This is why swing states are so important to the canditates, they know that the chances of them winning the votes in the other party's states are almost impossible, so they must gather all of the votes they can from the states that are known for their swing-like tendencies. It also goes the other way, each candidate trusts that their own party's states will vote for them, so there is no need to waste the money and campaign. Unless its the primary elections, candidates don't typically campaign where they know that the votes are all but set in stone. It's like going grocery shopping, if you know that you are allergic to peanut butter and you already have all the jam you need, you will only go for the special bread that everybody fights for right? The candidates are the same, they don't go after what they already have and what they can't have, only what they might earn, or else it's just a waste of money, so nobody should be able to complain about a candidates campaigning.
