Trump wins US Republican primary in Nevada. Nikki Haley experiences a debacle.

How did the oddity come about that Trump and Haley are both running in the Republican primaries in Nevada - but are on different ballot papers and are standing for election on two different days? How could that even be? And what does this mean for the Republican presidential nomination in November? The background is a dispute between the Republican Party and the state. The next Republican primary is now scheduled for both at the same time in South Carolina.
