What the GOP should worry about is the intoxication that adoring crowds often induce in politicians. Palin might board the bus intending to pull a Trump and disembark convinced that now, more than ever, the nation requires her service. The hosannas ringing in her ears might deafen her to voices of reason.
Odds are it won’t happen. But the fact that Palin’s ego trip so easily stole the spotlight from the actual Republican candidates shows what a challenge the party faces in trying to deny President Obama a second term.
