From day one, I have always been open about my sexual orientation.

I’ve decided to run for the U.S. Senate because I believe Wisconsin families need a senator who will work hard to deliver results for the middle class - a leader with the courage to do what’s right, no matter how tough the odds or how powerful the special interests we have to fight.

When I first ran for Congress in 1998, people counted me out.

Politicians in Washington and Madison aren't hearing, aren't listening to their constituents and prioritizing getting people back to work and growing our economy.

Americans are not saving enough for retirement.

All my life, the naysayers have told me that I can't win because I'm a progressive... because I'm a woman... even because I'm a lesbian.

I have no idea what goes on in another person's mind. As a legislator, I need to be good at persuading people, counting votes and getting to 50 percent plus one. I don't go back and say, 'Why did this person get to the right position?' It's only, 'Are you yes or are you no?

I find it greatly disturbing that the Bush administration has used political and religious ideologies to influence national policy on science and medicine.
