On the trail

Martin O'Malley, a former Maryland governor and former Baltimore mayor, pulled out of the presidential race after the Iowa caucuses on Monday night, but he said the party must "hold strong" behind the eventual nominee. He said that Democrats must stick to their beliefs. Hillary Clinton wished him the best and called him "a great public servant."

Sen. Bernie Sanders said before the votes were counted that if rival Hillary Clinton "ends up with two delegates more of many, many hundred delegates, you tell me why that's the end of the world?" He added, "We are in this to win at the convention. We're taking this all of the way."

Hillary Clinton stopped by a campaign office in south Des Moines early Monday to rally her troops. Bearing iced coffee and doughnuts, Clinton and her daughter, Chelsea, mingled and snapped selfies with volunteers. "I had to stop by and tell you how much I appreciate your hard work," Clinton said. "I thought I'd bring you some unhealthy snacks!" Nearly 9,000 campaign volunteers knocked on 186,000 doors in Iowa over the past three days.

Former President Bill Clinton spent part of Monday lowering expectations — and applying a little pressure — in anticipation of the Feb. 9 New Hampshire primary. Bernie Sanders, who's from neighboring Vermont, has a big lead there. New Hampshire voters, Bill Clinton said, "never voted against anybody from next door except when an incumbent president asked them to do something else." He was dubbed the "comeback kid" after his performance in New Hampshire in 1992 — but he came in second to Paul Tsongas from neighboring Massachusetts.

Actor Josh Hutcherson, star of the "Hunger Games" films, campaigned in Iowa for Bernie Sanders. The indie band Vampire Weekend and actress Susan Sarandon also made appearances for him. Actress Jamie Lee Curtis stumped for Hillary Clinton.
