According to the American Spectator:
Senior staff to Wesley Clark rose in objection on Wednesday evening and Thursday morning on news from their former candidate that he intended to endorse Sen. John Kerry for the Democratic nomination.
Clark told his senior staff that he had talked to Kerry and that he intended to back his former competitor. Clark never spoke to other Democratic hopefuls Sen. John Edwards and former Vermont Gov. Howie Dean.
Perhaps the most stung by Clark’s decision was his senior adviser Chris Lehane, who prior to joining Clark’s staff had briefly advised Kerry’s campaign.
Lehane is now the focus of a media whirlwind over negative stories about Kerry he is said to have spun to reporters over the past few weeks.
