Then the motives of all the factions are irrelevant, and we'll just have to decide on his merits whether or not Lott is a liability.
Personally, I think Lott's been an ineffective GOP Senate Leader, whether in the Majority or the Minority. Still, I'd have rather seen him coast through another two years at the helm than step aside under this cloud.
Now, coasting is no longer an option. Leadership is no longer an option. Lott made this mess, and now he needs to suck it up and and take the path of humbled honor...
And it's likely that no one but Bush can get him to take it.
