Cruz finished 1st in Iowa. He won 8 delegates. Trump and Rubio came in 2nd and 3rd, respectively, and each walked away with 7 delegates. Ben Carson got less than half of Rubio's caucus ballots, but hauled in 3 delegates. Total delegates at the convention will be 2472, 1237 needed to nominate.
Funny how unimportant Iowa has become to Trump supporters.
