This today from Sarah Palin reminded me of that great moment when she spoke at the 2008 Republican National Convention and of why, after she stirred the affection of the skeptical, the election had a sudden burst of energy and shift in momentum.  But it also reminded me of how quickly that momentum dissipated as she kept talking.  The twelve-year-old in me wants to rejoice in the zinger . . . and she does rejoice in it and she loves Sarah Palin for giving her that sometimes desperately needed satisfaction--like a tall drink of something better than water.  But then I remember that I am no longer twelve, that twelve-year-olds shouldn't drink like that anyway, and that real political persuasion consists of more than zingers.  Still . . . they are sometimes useful and lovely--in their way and in their place--as is Sarah Palin.  I am hoping that her willingness to speak like this indicates that she has happily figured this out, too.
