“ INDIANAPOLIS: Hillary Clinton is in the midst of a poignant farewell to let her supporters down gently. It’s one of the greatest gifts she could give Barack Obama. Quitting immediately after this week’s poor showing would create a great risk that her supporters - particularly women - would never throw their lot in with Obama as the Democratic Party’s nominee. But Clinton can start subtly selling Obama to her supporters over the last few weeks of her campaign. Sources indicate she will start taking the high road until the primary process ends on June 3.
