WHAT if a presidential candidate held what she billed as “the largest, most interactive town hall in political history” on national television, and no one noticed?

The untold story in the run-up to Super Tuesday was Hillary Clinton’s elaborate live prime-time special the night before the vote. Presiding from a studio in New York, the candidate took questions from audiences in 21 other cities. She had plugged the event four days earlier in the last gasp of her debate with Barack Obama and paid a small fortune for it: an hour of time on the Hallmark Channel plus satellite TV hookups for the assemblies of supporters stretching from coast to coast.

The same news media that constantly revisited the Oprah-Caroline-Maria rally in California ignored “Voices Across America: A National Town Hall.” The Clinton campaign would no doubt attribute this to press bias, but it scrupulously designed the event to avoid making news. Like the scripted “Ask President Bush” sessions during the 2004 campaign, this town hall seemed to unfold in Stepford. The anodyne questions (“What else would you do to help take care of our veterans?”) merely cued up laundry lists of talking points. Some in attendance appeared to trance out.

But I’m glad I watched every minute, right up until Mrs. Clinton was abruptly cut off in midsentence so Hallmark could resume its previously scheduled programming (a movie promising “A Season for Miracles,” aptly enough). However boring, this show was a dramatic encapsulation of how a once-invincible candidate ended up in a dead heat, crippled by poll-tested corporate packaging that markets her as a synthetic product leeched of most human qualities. What’s more, it offered a naked preview of how nastily the Clintons will fight, whatever the collateral damage to the Democratic Party, in the endgame to come.
