Either he is a rascist. Or he is very, very stupid. Reminds me of that line by DeNiro in "Casino" about the slots manager:
"If he knew about it, he's gone. If he didn't know, then he's too stupid to stay. Either way, he's gone."
With all due respect to Vannrox, I believe your analysis is correct. Lott may be a dolt but he's proven himself unable to control his tongue. All that talk about him resigning his Senate seat is just that. Talk.
It may not be Lott's choice to resign his seat. The next step in the process will be a call for censure and there is no way republicans can keep it from coming to a vote. Lott would have no choice but to resign given the a high probability that a censure vote would go against him Democrats have let republicans do the dirty work in regard to the Majority Leader question, they will pick up the ball from this point on. They have all the "evidence" they need to convict Lott of racism wrapped up in a nice little package and given to them by republicans as a Christmas present.
