I am still fuming at the rank amateur the party ran against Mikulski and the total nonenity they ran against my Congressman, Sarbanes in 2010. I remember seeing one or two road signs for the former. As for the latter, I never heard his name again once he won the primary.
Although I'm not a VA resident, I would have considered Ollie North qualified for his senate run based simply on his insider knowledge and experience. While this guy may not have had his fingers directly in the inner workings as Ollie did, I'm guessing his position gave him access and familiarity to a lot of issues and policy decisions that most conventional candidates could only dream about.
I would have said the same thing about Gary Aldrich back in the Clinton days. While I generally prefer our legislators to come from the private sector (minus lawyers), if they must run for office coming off a government career, I'd much prefer it be somebody who actually served in a real world capacity (i.e. Alan West) than some policy-wonk bureaucrat.
