It's interesting that the Reuters story on the Miers nomination, "Bush pick for high court outrages conservatives," mentions Abe Fortas:
Manny Miranda, head of a conservative coalition called The Third Branch Conference, said Miers was "the most unqualified choice" for the high court since Lyndon Johnson tried to make Abe Fortas chief justice in 1968.
Fortas's name came up in the discussions over the judicial filibuster. He is the only Supreme Court nominee ever filibustered, though it was a bipartisan effort without support of either party's leadership.
The Republicans are still itching to pull the trigger (the poorly named "nuclear option") on a Democratic judicial filibuster, an opportunity much more readily available had Bush nominated someone in the mold of Thomas or Scalia, both of whom he has explicitly praised. But judging from initial reaction, it sounds that in the impossible event Harriet Miers were to draw a filibuster, it would be more likely to come from conservatives rather than liberals.
It's hard to know which side of the fence Bush is playing. The line between genius and sheer stupidity is often very fine.
