The latest news from Cuba is that 10% of its population has left the island in the last two years. That's a stunning level of exodus, topped only by nations in total collapse like Venezuela and Syria. And yet, as we have seen in Syria, when a totalitarian regime switches to "bitter end" mode, a nation can get stuck at this level of misery for decades without the hoped for regime change happening. In Cuba, the USA can declare victory. American style capitalism won, Cuban style Marxism lost. It's time to change tactics to bring about the final regime change. If the USA drops its embargo, the Cuban government will lose its last excuse for why its economy's failures are not the government's fault. And allowing free movement of peoples, on the same conditions that the USA applies to other Caribbean nations, will put millions of Cuban citizens face-to-face with happy, wealthy Cuban Americans, living proof that a better way of life is possible for Cuba. And even if it doesn't lead to a regime change in Cuba right away, it's still worthwhile. Cuba would no longer have any incentive to threaten the USA militarily or through terrorism, so there's no downside risk to opening up. And the act of magnanimity would send a strong message to the other nations of the world that the USA is negotiating from a position of confidence and not fear.

The question asks if there's "a chance." Of course there is - he's on the ballot!
