Sarah Palin is communicating these days on Facebook. Yesterday, she weighed in on Obamacare—worrying about its rationing implications, certainly a legitimate concern. But she used incendiary and frankly, amateur-sounding terms like “death boards” and “evil”—that are both over the top and unlikely to convince anyone but the already converted to oppose the current legislation. It seems to me that if she hopes to become an influential national leader, she needs to professionalize her approach. That doesn’t mean becoming bland. But it does mean elevating the discourse and exhibiting a more deliberate and substantive brand of leadership.
