Eugene Robinson: Democrats have some thinking to do after Tuesday's elections, but Republicans don't have time to think. They're too busy trying to survive the party's internal purge and avoid being shipped off to political Siberia. Will loyal members inform on others for harboring suspiciously moderate views? Will anyone judged guilty have to wear a sign saying "Republican In Name Only" as penance? Will there be re-education camps? Will deviationists face the Enhanced Interrogation Technique of being forced to listen to the wit and wisdom of Glenn Beck, at ear-splitting volume, for days on end? Or worse: When Sarah Palin's memoir, "Going Rogue," hits bookstores later this month, will the ideologically impure be required to read -- and commit to memory -- every golden word?
