Two very different but ultimately very aligned versions of GOP mendacity were on display this week. At one end stands Newt Gingrich. A former college history professor, Gingrich is articulate and knowledgeable. But that didn't stop him from misrepresenting shoe-bomber Richard Reid's citizenship in an effort to paint President Obama as a soft-on-terror "radical" -- or tie logic in knots trying to justify his "mistake" after the fact. At the other end of the spectrum is Sarah Palin -- so clueless she feels the need to make crib notes about boilerplate talking points. She too is willing to completely discard truth, evidence, logic, and the facts to score cheap political points. These two appear destined to compete for the 2012 Republican nomination. Or perhaps they can join forces and form a veracity-vanquishing dream ticket -- two peas in a prevaricators' pod.
