In each state you only need >50% of the votes to win all the electoral points for that state. Once you have 50% of the votes in a state, additional votes within that state are essentially worthless. In Hillary’s case her supporters were heavily clustered in a handful of states. She won California by a landslide, for example, but then went on to lose in a bunch of other states by narrow margins. If her supporters had been spread out among more states she would have easily won the overall election.
