We need to teach our kids that it's not just the winner of the Super Bowl who deserves to be celebrated, but the winner of the science fair.

I think that the Democratic Party is a big tent, which means that there are positions I may not agree with.

Marco Rubio is one of those people. How does that work? How can you call him a con artist and dangerous, and object to all the controversial things he says, and then say, but I`m still going to vote for him? Come on, man.

America is not the crude stereotype of a self-interested empire. Given our interdependence, any world order that elevates one nation or group of people over another will inevitably fail.

I will begin to remove our troops from Iraq immediately.

On this Thanksgiving, as we spend time with our family and friends, let's all reflect on what we're thankful for in our own lives. And let's remember those who cannot be with their loved ones because they're serving overseas. But let's also do our part to help those who have no place to go for a meal. I encourage all Americans to do what they can to help those in need-because the best way to show our gratitude for what we have is by doing our part for those who have less.

The issue of climate change is one that we ignore at our own peril. There may still be disputes about exactly how much we're contributing to the warming of the earth's atmosphere and how much is naturally occurring, but what we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return. And unless we free ourselves from a dependence on these fossil fuels and chart a new course on energy in this country, we are condemning future generations to global catastrophe.
