USSC Research Editor Victoria Cooper talks to 2SER about Donald Trump's historic victory in the Iowa caucuses. Cooper says that Iowa's demographics have shifted in recent years, with an older population and increasing share of white evangelicals who seldom or never go to church.

"Iowa in 2012 actually voted for Obama by 6 percentage points so it's gone on to completely flip. In 2020 Iowa voted for Trump by 8 percentage points."
