(Radio Iowa) — Democratic presidential candidate Cory Booker will wrap up his four-day bus tour of the state this (Monday) afternoon with a holiday party at his campaign headquarters in the Des Moines suburb of Urbandale. During a stop in Ottumwa Sunday night, Booker delivered his unity message. “If you Caucus for me, if you stand with me in this fight, I promise you that we will fight the only way I know how, which is bringing people together,” Booker said.

And Booker suggested Democrats will lose if the message is anger. “The last thing America needs is for our party to out-Trump Trump,” Booker said. “I don’t want to do that. You know what Martin Luther King said. It’s so beautiful: ‘Darkness cannot drive out darkness.’ Only light can do that.”

Booker’s other stops today (Monday) are in Mount Pleasant and Indianola. Pete Buttigieg will hold a town hall meeting this (Monday) afternoon in Ankeny. There will be a three-day lull on the Iowa Caucus campaign trail on the 24th, 25th AND 26th, then Joe Biden and Amy Klobuchar return to the state on Friday the 27th. Klobuchar is making stops in three counties on Friday — and will complete a 99-county tour of the state.
