She could have used the tragic events of January 8th, 2011 as a way to vilify those opposing her and her party, such as the Tea Party movement (as many unscrupulous, opportunist progressive and left-wing commentators attempted to do after she was shot). She could have stood for re-election, despite the restrictions imposed on her by her injuries, and won in a landslide sympathy vote. She could have allowed the usual suspects to use her as a spokesperson for their populist anti-Second-Amendment campaigns.
Instead, Rep. Gabrielle Giffords turned aside from all those negatives, and chose to emphasize and accentuate the positive. She's given notice of her intention to resign her Congressional seat in order to pursue further healing.
I'm impressed, notwithstanding my many and deep-rooted political differences from Rep. Giffords. There are too few classy politicians in Washington. I'm sorry we've lost one of them.
