Now with state-by-state winner-take-all laws (not mentioned in the U.S. Constitution, but later enacted by 48 states), Wyoming, like 23 of the smallest states, is politically irrelevant in presidential general elections.

In 2012, 24 of the nation's 27 smallest states received no attention at all from presidential campaigns after the conventions. They were ignored despite their supposed numerical advantage in the Electoral College. In fact, the 8.6 million eligible voters in Ohio received more campaign ads and campaign visits from the major party campaigns than the 42 million eligible voters in those 27 smallest states combined.  

The 12 smallest states are totally ignored in presidential elections.  These states are not ignored because they are small, but because they are not closely divided “battleground” states.
