The newest ad from Bob McDonnell stars a very special supporter: Sheila Johnson, a female African-American businesswoman and self-identified Democrat supporting a Republican -- and who also has publicly told jokes about Democratic candidate Creigh Deeds for stuttering.

The content of Johnson's ad isn't remarkable by itself -- she talks about how she understands what it takes to run a business, and how McDonnell is a bipartisan leader who can grow the economy and create jobs.

The really fun thing is that she refers to herself as a "Democrat businesswoman" -- note the phrasing usually favored by Republicans as an epithet -- and alternately pronounces her candidate's name as "McDonnell" and "McDonald."
