Each state has a number of votes in the Electoral College equal to two more than its number of representatives in the U.S. House.
And, each state, however small its population, gets a minimum of one member of the House. As the state with the smallest population, WY voters get relatively more clout than others.
The smaller the population per electoral college vote, the greater the clout per person. For WY, the figure is 192,920 people per ECV. The closest rival is VT with 207,996 per ECV. At the other end of the scale, TX is the loser with 763,050 per ECV.
Following this year's census, those numbers will change marginally. These are based on 2019 estimates.
