With five winners in Iowa, the race for the White House has justbecome much more interesting

Last night the Iowa Caucuses marked the beginning of the presidential primary season in earnest. Ted Cruz came out on top for the Republicans, and Hillary Clinton narrowly leads Bernie Sanders for the Democrats. Reflecting on the Iowa results, US Centre Director Peter Trubowitz writes that Donald Trump and Marco Rubio were also winners, and that Clinton and Sanders’ close result means that the race between the two may be about to become much more heated.
