The White House now displays the message discipline of a summer camp as it denies the clear signal by Kathleen Sebelius that it is in retreat on healthcare. Sebelius clearly pointed to the casting away of the public insurance option on the Sunday CNN show. POTUS signaled the same in an op-ed, calling it a "sliver." Now, the day after, the White House zig-zags by e-mailing members of Congress that it continues to support and desire a public insurance option.   I am not going to look for anything cunning or sinister. The Politburo messaging failed in the August heat of battle. There will be a sluggish, petulant recovery campaign; but the result will be stalling and compromise.  The public insurance option is no longer viable.
