You really think the Democrats would fillibuster the first black woman (and single mom) nominated to the court?
They'd threaten, but no way would they do it - not with the spike in the black vote for Bush in 2004. They remember that, and "the trends is your friend".
Usually, yes. But, yeah, they'd filibuster any overt conservative with a record---and that's what they won't have on Miers. Remember, "black" is not a skin color . . . it's a state of mind :)
