Kyle Olson's The American Mirror site recounts a Nancy Pelosi appearance in New York at which she suffered several "senior moments." Specifically, instances where she lost her train of thought and paused awkwardly, groping for words. Hat tip to Drudge Report for the link.
Various theories have been proposed for Pelosi's recent fogginess. My favorite is this: botox overdosage toxicity, causing not just facial miniparalysis but brain miniparalysis. Others claim to see early-stage Alzheimers, something so ugly I wouldn't wish it even on the uber-harpy of progressives.
