History of Wyoming
The UP reached the town of Cheyenne, which later became the state capital, in 1867. The railroad eventually spanned the entire state, boosting the population, and creating some of Wyoming's largest cities, such as Laramie, Rock Springs and Evanston. The railroad needed coal, which was discovered in quantity in the southwestern part of the state, especially around Rock Springs. In 1885, a murderous riot known as the Rock Springs Massacre broke out when white miners drove out Chinese miners employed by the Union Pacific Coal Company in Rock Springs.
2016 Wyoming Republican caucuses
Wyoming is the least populous of all 50 U.S. states. With almost 60% of the population identifying with or leaning towards the Republican Party, compared to less than 30% identifying with or leaning towards the Democrats, it is also the most solid Republican state, ahead of Idaho and Utah. In the 2012 presidential election, incumbent President Barack Obama received less than 28% of the votes, trailing Mitt Romney by more than 40 points.
