The problem these guys had was not someone forgetting to sign up.
Even though they both may have had the required number of voters on the Virginia GOP required petitions, they missed by having some of their workers NOT being registered Virginia voters, a requirement that seems to have been changed less than 30 days before the deadline to submit petitions.

This whole thing has an odor of a fix being in for Romney.
