This is true today. If only half of the population of the top five states voted, then they would decide the outcome of the presidential election. These states are California (38 million), Texas (28 million), Florida (21 million), New York (19 million) and Pennsylvania (about 12 million). Maryland, at No. 19 on the list, has about half the population of Pennsylvania. People living in Wyoming and Vermont (around half a million each), might as well stay home on election day.
