Donald Trump was leading the polls in Iowa, but on caucus night, it was Ted Cruz who came away with the first-place win. “Iowa has sent notice that the Republican nominee and the next president of the United States will not be chosen by the media, will not be chosen by the Washington establishment,’’ Cruz crowed. New Hampshire, the next contest, is not necessarily Cruz country, but he spent the week campaigning gamely there nonetheless — flattering voters and comparing himself to Ronald Reagan in 1980. Win or lose up North, Cruz’s Iowa win sets him up to do well in more conservative, religious South.
