Washington (CNN)Martin O’Malley is expected to emphasize his “youthfulness,” and a less scripted, more accessible presidential campaign, as a way to help contrast his candidacy with Hillary Clinton in the race for the Democratic nomination, an O’Malley confidante tells CNN.
“We do think there is a real generational argument to make and that he can seize upon it,” said the source, who spoke on the condition of anonymity.
O’Malley, 52, announced Tuesday on two social media platforms, Snapchat and Twitter, that he would make a “special announcement” on May 30 in Baltimore — when he is widely believed to formally enter the 2016 contest. Clinton, the former Secretary of State and Vermont Sen. Bernie Sanders are already in the race for the Democratic nomination.
