In fact, I was moved — for the first time in my life — to actually write a letter to a sitting president:
Mr. President: I want to thank you for moving quickly on closing Guantanamo and CIA black sites, on lifting the global gag order and endorsing stem cell research, and on committing your administration to transparency and openness. I knew these were your values and goals when I was knocking on doors and making phonecalls, but it's gratifying to see them so decisively reaffirmed in your first days in office. I know there will inevitably be setbacks, but I look forward to great things ahead.
I could've gone on at greater, more effusive length (no big surprise to those who know me), but the contact form at the White House website has a 500 character limit.
Oh, well... suffice it to say that Obama's first 50-some hours in office show him to be a man who knows there's work to be done.
