"Allow him to stay as a Senator?"
Good Lord... Jackson Lee and Cummings aren't even Senators themselves. Don't you think you're over-dramatizing just a bit?
Actually, I think you and your cohorts calling for Lott to step down are.
If you think Lott, humiliated by being forced to step down as Majority Leader by essentially admitting he's a racist, will want to continue to serve as a Senator, I'd ask you:
Would you continue to serve?
Perhaps you should pay a little more attention to the outrageous demands being made of Lott from the Congressional Black Caucus.
