It's time to let science and medicine, not politics and rhetoric, lead us to good, sound policy.

Sometimes in politics, you think you've seen it all. Turns out I was wrong.

Any reasonable economist will tell you that it's nearly impossible to isolate the impact of right-to-work laws on a state's job growth. A multitude of other factors intervene. However, one thing the numbers can show is that right-to-work laws have a negative effect on the wages of workers in that state.

Power must be used, but it must be tempered by soul-searching and the recognition of our human capacity for error. That is the maxim that should inform our approach to every challenge, from reforming state government to engaging in foreign affairs.

Tax rates for the wealthy should revert to Clinton-era levels, both because it is necessary for long-term deficit reduction and because fairness dictates it. Moreover, there is no proof that higher marginal rates dissuade investment, all the rhetoric from the Right notwithstanding.

A year is an eternity in politics - though less than a moment in history.

I believe in an evolving Constitution. A flexible Constitution leaves room for us to consider not merely how the world once was, but how it ought to be.
