In the annals of twitdom, Congresswoman Gabrielle Giffords (Democrat, Arizona) must rank near the top for her question to General Petraeus about how he was planning to reduce carbon emissions in the War on Terror. This politician is a poster child for term limits, and another sterling example of an elected representative attempting to capitalize on the issue de jour of her (apparently) head-in-the-sand constituency without bothering to think. Though in Giffords’ defense, her constituents may not have elected her based on her cognitive powers. Sounds like our local politics.
