From Truthdig (an excellent site), I learn that my Senator Tom Harkin and neighboring congressman Bruce Braley voted against the Defense Authorization Act that allows the government to hold citizens without trial. My compliments to them (and I've sent them emails saying so) for their courage & wisdom in so voting.
I'm deeply disappointedthat my Representative Dave Loebsack (D) voted in favor of the act. I wrote him so, too. My disappointment, not quite so sharp, that Senator Grassley voted in favor of this. Actually, I used to have a grudging admiration for Grassley, who showed some independence, but now he simply goes with the crowd, even though he's safe for another 5 years. Sad, but true.
Truthdig links to sites that can tell you how your representatives voted, and I suggest you let them hear from you.
P.S. My earlier post expressed my disappointment with Obama.
