Barack Obama officially declares his candidacy

Poverty, Health Care, Energy Independence are central themes in his announcement speech.

All of us know what those challenges are today - a war with no end, a dependence on oil that threatens our future, schools where too many children aren't learning, and families struggling paycheck to paycheck despite working as hard as they can. We know the challenges. We've heard them. We've talked about them for years.

...

For the last six years we've been told that our mounting debts don't matter, we've been told that the anxiety Americans feel about rising health care costs and stagnant wages are an illusion, we've been told that climate change is a hoax, and that tough talk and an ill-conceived war can replace diplomacy, and strategy, and foresight. And when all else fails, when Katrina happens, or the death toll in Iraq mounts, we've been told that our crises are somebody else's fault. We're distracted from our real failures, and told to blame the other party, or gay people, or immigrants.

....

Let's be the generation that finally tackles our health care crisis. We can control costs by focusing on prevention, by providing better treatment to the chronically ill, and using technology to cut the bureaucracy. Let's be the generation that says right here, right now, that we will have universal health care in America by the end of the next president's first term.

Let's be the generation that finally frees America from the tyranny of oil. We can harness homegrown, alternative fuels like ethanol and spur the production of more fuel-efficient cars. We can set up a system for capping greenhouse gases. We can turn this crisis of global warming into a moment of opportunity for innovation, and job creation, and an incentive for businesses that will serve as a model for the world. Let's be the generation that makes future generations proud of what we did here.

....

We can work together to track terrorists down with a stronger military, we can tighten the net around their finances, and we can improve our intelligence capabilities. But let us also understand that ultimate victory against our enemies will come only by rebuilding our alliances and exporting those ideals that bring hope and opportunity to millions around the globe.
