The Obama White House made an unfortunate and ungracious choice in launching a preemptive attack on Rick Perry’s nomination this week. Spokesman Josh Earnest did his best deadpan as he disparaged the choice as one based on politics and not merit.

But what about President Obama’s appointments of Ken Salazar, Kathleen Sebelius, Tom Vilsack and Janet Napolitano? They were all lawyers without specific expertise in the issue areas of the departments they led. But each, having experience as elected Democratic statewide officials, knew enough about their respective issue areas that their status as non-experts never really mattered.
