Rush Limbaugh, just now. "Biden did exactly what was desired, and in the process hurt himself and Obama.... His job was to excite the base.... They came out of their shell: none of this compassion and understanding... The base wants blood. The base wants rude.... Biden gave them exactly what they wanted."
UPDATE: How it looked, per Rush: "Paul Ryan was a son who was a little embarrassed for his father... trying to tell his dad that the world has passed him by" without subjecting him to public humiliation.
