During his acceptance speech at last night’s Democratic National Convention, President Barack Obama presented a set of policy goals (and related achievements) that would be his focus, if reelected President…

I’m asking you to rally around a set of goals for your country – goals in manufacturing, energy, education, national security, and the deficit; a real, achievable plan that will lead to new jobs, more opportunity, and rebuild this economy on a stronger foundation. That’s what we can do in the next four years, and that’s why I’m running for a second term as President of the United States….
We’ve opened millions of new acres for oil and gas exploration in the last three years, and we’ll open more. But unlike my opponent, I will not let oil companies write this country’s energy plan, or endanger our coastlines, or collect another $4 billion in corporate welfare from our taxpayers. We’re offering a better path – a future where we keep investing in wind and solar and clean coal; where farmers and scientists harness new biofuels to power our cars and trucks; where construction workers build homes and factories that waste less energy; where we develop a hundred year supply of natural gas that’s right beneath our feet. If you choose this path, we can cut our oil imports in half by 2020 and support more than 600,000 new jobs in natural gas alone….
For the first time in a generation, nearly every state has answered our call to raise their standards for teaching and learning. Some of the worst schools in the country have made real gains in math and reading. Millions of students are paying less for college today because we finally took on a system that wasted billions of taxpayer dollars on banks and lenders….and together, I promise you – we can out-educate and out-compete any country on Earth. Help me recruit 100,000 math and science teachers in the next ten years, and improve early childhood education. Help give two million workers the chance to learn skills at their community college that will lead directly to a job. Help us work with colleges and universities to cut in half the growth of tuition costs over the next ten years….
Terrorist plots must be disrupted. Europe’s crisis must be contained. Our commitment to Israel’s security must not waver, and neither must our pursuit of peace. The Iranian government must face a world that stays united against its nuclear ambitions. The historic change sweeping across the Arab World must be defined not by the iron fist of a dictator or the hate of extremists, but by the hopes and aspirations of ordinary people who are reaching for the same rights that we celebrate today….And while my opponent would spend more money on military hardware that our Joint Chiefs don’t even want, I’ll use the money we’re no longer spending on war to pay down our debt and put more people back to work – rebuilding roads and bridges; schools and runways. After two wars that have cost us thousands of lives and over a trillion dollars, it’s time to do some nation-building right here at home….
Independent analysis shows that my plan would cut our deficits by $4 trillion. Last summer, I worked with Republicans in Congress to cut $1 trillion in spending – because those of us who believe government can be a force for good should work harder than anyone to reform it, so that it’s leaner, more efficient, and more responsive to the American people. I want to reform the tax code so that it’s simple, fair, and asks the wealthiest households to pay higher taxes on incomes over $250,000…And I will never turn Medicare into a voucher. No American should ever have to spend their golden years at the mercy of insurance companies. They should retire with the care and dignity they have earned. Yes, we will reform and strengthen Medicare for the long haul, but we’ll do it by reducing the cost of health care – not by asking seniors to pay thousands of dollars more. And we will keep the promise of Social Security by taking the responsible steps to strengthen it – not by turning it over to Wall Street.

Two of the questions about policy goals are the same for the incumbent as they were for the challenger: are these things that government should be doing, are these things that government can be reasonably expected to do. We’ll modify the third question slightly, and ask where both change and continuity can be seen, relative to the incumbent’s first term. (Actually, that’s probably the right question to ask a challenger too).
