Tuesday night's Democratic debate in Iowa was a civil affair, with the six participating candidates mostly avoiding going after each other. The race's four frontrunners — former Vice President Joe Biden, Sen. Bernie Sanders (I-Vt.), Sen. Elizabeth Warren (D-Mass.), and former South Bend, Indiana, Mayor Pete Buttigieg — were joined onstage by Sen. Amy Klobuchar (D-Minn.) and billionaire Tom Steyer. Warren made a case for a female candidate beating President Trump and said she supports the USMCA trade deal as a "modest improvement" over NAFTA. Sanders said a conflict with Iran could be "even worse" than the Iraq and Vietnam Wars. All of the candidates agreed that child care in the United States must be reformed, with most saying it should be affordable or even free, and they touted their climate change plans.
