In Nevada, Donald Trump assured of increasing his advantage to run for the White House. Republican residents are in fact offered not one possibility of voting to decide between the candidates, but two: first a primary on Tuesday, then caucuses on Thursday.

An electoral system is so complicated that even Americans have difficulty understanding it. Results from the primaries, both Republican and Democratic, are expected around 7:00 p.m. Tuesday (03:00 GMT Wednesday). Those for the Republican caucuses are to be announced Thursday, according to the party.
