State of the race
Last week, media outlets proclaimed Hillary Clinton the presumed Democratic presidential nominee after her decisive victories in the New Jersey and California primaries. Despite calls to drop out and a Clinton endorsement from President Barack Obama, Bernie Sanders vowed to continue to compete against Clinton in this week's D.C. primary. Meanwhile, Clinton is focused on uniting the Democratic party behind her in order to square off against Republican nominee Donald Trump.
