9:35 p.m.: The first results expected after 7:00 p.m. (2:00 a.m. in Paris)
There will be no trend before, because it is a caucus: this means that the voters all meet at 7:00 p.m. (2:00 a.m. in Paris), then listen to a pitch from a representative of the candidates and vote immediately. We will very quickly have the first results from rural constituencies (where there can only be 10-20 voters), which should favor Donald Trump. For the big cities (Des Moines, Cedar Rapids), it will be a little later, and Nikki Halley could go up a little, because she is more popular in the suburbs with the moderate electorate (and independents who have the right to vote in Iowa).
