And here resides the grandest irony:
The most rational of candidates was undone by her transparent efforts to navigate the unreasoning fervor of an unyielding minority for an uncompromising vision which, if adopted, would likely doom any Democrat in a general election.
Yet given that the coalition Warren needed to build started by competing with Sanders for progressives, she felt as though she had no alternative.
But the tortuous path she took bled support on both sides, tarnished her aura as the principled master of policy, and intensified misgivings among the many primary voters focused on electability. So here she is now, hostage to impeachment a few days from the Iowa caucuses, unable to conduct the around-the-clock campaign which might revive her prospects.
