Left-leaning bloggers have had a tremendous impact on the Democratic Party.

Facebook's headquarters is a two-story building at the end of a quiet, tree-lined street. Zuckerberg nicknamed it the Bunker. Facebook has grown so fast that this is the company's fifth home in six years - the third in Palo Alto. There is virtually no indication outside of the Bunker's tenant.

It's not my job to worry about how Left, Right will react to something. My job is, am I creating something that connects people? That's my job.

Culture is about humanizing people. You look at the African-American civil rights movement, you look at the LGBT rights movement - the culture changed before the politics did.

My philosophy comes from a worldview that looks at the world as one. It's a holistic view that sees the world as interconnected and interdependent and integrated in so many different ways, which informs my politics.

My parents' example of a loving, caring relationship, I think, has affected my songwriting a ton and allowed me to start writing love songs that people could connect to without sounding like you're being cheesy, because they're coming from a real place, something that I saw coming up. I think they're a huge influence on my songwriting.

Government is taking 40 percent of the GDP. And that's at the state, local and federal level. President Obama has taken government spending at the federal level from 20 percent to 25 percent. Look, at some point, you cease being a free economy, and you become a government economy. And we've got to stop that.

The kind of cynical politics of divide and conquer, that's shameful stuff, and I don't know - people live their life like that, but I don't know how they look back and feel good about themselves.
