MARY KATHARINE HAM: Maryland exchange director resigns, was on Caribbean vacation when it imploded. “Did you catch that? It’s not like she had a vacation planned for right after the exchange launched assuming things would go fine, which would have been irresponsible enough. She waited until it failed, the heat got turned up on her staff, and then peaced out and claimed she had not e-mail or phone access. Because the Caribbean is so famously remote.”
