White House candidates brace for Iowa vote

Months into the Democratic nomination marathon, after seven debates, countless rallies, bitter candidate clashes and an impeachment effort to remove the US president, Iowa was set to hold the first-in-the-nation vote yesterday to see who challenges Donald Trump in November. More than two dozen White House hopefuls began the journey, some as early as a year ago. Eleven now remain, exactly nine months from Election Day. Despite the historically diverse field consisting of men and women of color and young candidates with little Washington exposure, the two frontrunners are septuagenarian white men -- Bernie Sanders and Joe Biden -- with more than 80 years of political experience between them.
