I am a Democrat and I love my party and I want them to have good policies and good candidates, so I hope to be supportive in some way, but I don't intend to be any kind of 'godfather' or something like that.

When I first arrived to Congress in 1975, I would spend several hours every week with Republicans - having lunch, drinking a beer. But by the time I left last year, that was a rarity. Every moment of free time is eaten up by fundraising. And the advent of all these groups that can threaten passage of this or that with an avalanche of money or a primary opponent has poisoned our politics.

[A]s we celebrate 75 years of the minimum wage, we must also recognize that it is no longer achieving its potential impact in our economy or for America's working families. Every American deserves the chance to build a better life for his or her family - and raising the minimum wage will provide that opportunity.

It's been years, but I still say that I went out with the same progressive values and liberal ideals that I went in with. I made a couple of mistakes, I will honestly admit. In retrospect, there are a few votes I wish I could take back. But, through it all, I kept my support for organized labor, I kept my support for income equality, I kept my support for making sure that kids that come from poor families have access to education. So, yes, I still believe that you don't have to give up your ideals and go along. One person can still stand up and make a difference.

That signal's come and gone a lot in my life-time, that prairie progressivism died . I think prairie progressivism is still there. Every once in a while, odd things take place.

The burning issue of our time is the growing inequality in income and wealth in our country, and it's got to be addressed. We've got to stop it. It's eroding our politics. It's separating our society into the haves and the have-nots. It's condemning a whole younger set of our population to not be able to enter the middle class. And, it hits hardest in the prairie areas of the United States, our small towns and communities, where the jobs just aren't available and the incomes are low.

There's no one silver bullet, but money really is the root of all evil. The single biggest problem is how much more money is flooding into politics these days. It not only tends to enable a more extreme candidate to get elected, but because so much money is required to bankroll a campaign, everyone spends all their free time fundraising instead of reaching across the aisle.
