Bill Frist has an op-ed in today’s Washington Post headlined “The Zoo I Know.” Sounds like a provocative piece on what it’s like to be Senate Majority Leader. Except that it’s really about (drumroll please) the National Zoo in D.C. I suppose it’s okay for political leaders to have pet causes (no pun intended), but I wish Frist would spend more time figuring out how to get Bush’s judicial nominees confirmed and federal budgets trimmed.
