I am alumnus of Univ of Iowa. Sanders is very popular with students. And that precinct will put him over the top.
But Sanders will have much tougher time SC beating Hillary.
And Cruz will have tough time in NH & SC beating Trump.
New York values may work in New Hampshire but they won’t sell in South Carolina.
Iowa was an important Midwest bellwether and Cruz took it. He has strong chances on all southern states.
Trump needed Iowa. He didn’t get it.
