Hillary Clinton, once burdened with a profusion of image and credibility problems, has had a great many weights lifted off her shoulders this month. The Democratic presidential front-runner has defended her record at the State Department, dodged a serious challenge from Vice President Joe Biden and saw two of her primary opponents leave the race.

This week, Joe Biden said no, Jim Webb and Lincoln Chafee said no more, while Hillary Clinton endured 11 hours of Benghazi hearings aimed more at finding attack ad soundbites than facts. Meanwhile, Paul Ryan threw his hat into the ring for Speaker, but only after telling his House-mates, "I cannot and will not give up my family time." Bravo! It's a big moment when a political leader says that when he's about to take a big job rather than as a euphemism for being fired. Now Ryan should work to make it possible for all Americans to experience more family time. In the past, Ryan has opposed paid family leave, allowing America to remain the world's only developed country without it. So, as he seeks to unify the GOP caucus, he should also fight for family-friendly policies at a time when the country really needs them.

US presidential candidates have been invited to participate in the first-ever US Presidential Candidates' Forum held abroad, focusing on foreign and defense policy issues.

Farewell to dreams of the metric system becoming a campaign issue.
