DES MOINES, Iowa (AP) — Bernie Sanders says he’s ready to turn the political world upside down in Iowa.

The Democratic presidential candidate says that if his supporters turn out in large numbers for Monday night’s caucuses, “I think you’re going to look at one of the biggest political upsets in the modern history of our country.”

The Vermont senator is in a tight race with former Secretary of State Hillary Clinton.

Sanders tells CNN’s “State of the Union” that his campaign has gotten lots of people involved in politics who hadn’t been before. He mentions the working class as well as young people who no longer “want to sit back” but want to help direct their country’s future.
