Gotta know when to fold them, Senator Clinton. The more she campaigns against Obama, the more work Obama will have to do to turn people to him within the party.
The "fighting" Clinton should have materialized instead of the "experienced" Clinton at the beginning of the campaign, and would have made a difference in the voting for her. She simple chose the wrong theme at a time people are hurgry to change how things work in DC, rather than how to work things in DC. No one should force her out, but she needs to make that decision now. The money people like Sarah Kovner leaving the ship ought to give her a hint.
