FRANKFORT, Ky. — Calling her party's victory in the Kentucky governor's race a jolt of momentum for her own bid to unseat a Republican incumbent, Democrat Amy McGrath on Friday officially filed to challenge Senate Majority Leader Mitch McConnell in what looms as a bruising, big-spending campaign next year.

McGrath, a retired Marine combat pilot, touted many of the same issues — health care and good-paying jobs — that Andy Beshear highlighted in ousting Republican incumbent Matt Bevin in last month's election for governor. Beshear ran a “great campaign" that focused on issues that hit home for Kentuckians, McGrath said in a phone interview with The Associated Press.

“It absolutely gives us momentum because it shows that against an unpopular Republican incumbent, a Democrat can win," McGrath said. “And we win by talking about those bread-and-butter issues that Kentuckians really care about.

There is much that must be done to meet the test of this moment. But today I’d like to focus on two defining questions at the root of so many of our challenges -- whether the nations here today will be able to renew the purpose of the UN’s founding; and whether we will come together to reject the cancer of violent extremism.

First, all of us -- big nations and small -- must meet our responsibility to observe and enforce international norms. We are here because others realized that we gain more from cooperation than conquest. One hundred years ago, a World War claimed the lives of many millions, proving that with the terrible power of modern weaponry, the cause of empire ultimately leads to the graveyard. It would take another World War to roll back the forces of fascism, the notions of racial supremacy, and form this United Nations to ensure that no nation can subjugate its neighbors and claim their territory.

Recently, Russia’s actions in Ukraine challenge this post-war order. Here are the facts. After the people of Ukraine mobilized popular protests and calls for reform, their corrupt president fled. Against the will of the government in Kyiv, Crimea was annexed. Russia poured arms into eastern Ukraine, fueling violent separatists and a conflict that has killed thousands. When a civilian airliner was shot down from areas that these proxies controlled, they refused to allow access to the crash for days. When Ukraine started to reassert control over its territory, Russia gave up the pretense of merely supporting the separatists, and moved troops across the border.

This is a vision of the world in which might makes right -- a world in which one nation’s borders can be redrawn by another, and civilized people are not allowed to recover the remains of their loved ones because of the truth that might be revealed. America stands for something different. We believe that right makes might -- that bigger nations should not be able to bully smaller ones, and that people should be able to choose their own future...
