We know there are billions of stars and planets literally out there, and the universe is getting bigger. We know from our fancy telescopes that just in the last two years more than 20 planets have been identified outside our solar system that seem to be far enough away from their suns - - and dense enough - - that they might be able to support some form of life. So it makes it increasing less likely that we're alone. But if we were visited someday, I wouldn't be surprised.

We have seen a man dragged to death in Texas simply because he was black. A young man murdered in Wyoming simply because he was gay. In the last year alone, we've seen the shootings of African Americans, Asian Americans, and Jewish children simply because of who they were. This is not the American way. We must draw the line. Without delay, we must pass the Hate Crimes Prevention Act and the Employment Non-Discrimination Act. And we should reauthorize the Violence Against Women Act.

I tried marijuana once. I did not inhale.

We simply have to transition from an economy based almost exclusively on oil and coal and natural gas to one that's far more diversified, that uses solar energy, and wind energy, and the power of the tides, and bio-mass energy, and eventually, develops hydrogen.
