Better leading voices of the left please:
Liberal activists and academics ... say they are seeking candidates willing to mount a primary challenge against President Obama next year. The group, led by consumer advocate Ralph Nader and scholar Cornel West ... is seeking six “recognizable, articulate” candidates who would not mount serious challenges to Obama, but “rigorously debate his policy stands”...
LOL! They're seeking a challenger who would NOT mount a serious challenge! LOL!
