Miers would have been a conservative, hence President Bush nominated her.
GW Bush is a republican but he is a Moderate.. he has never been a conservative, he just uses the word in his speeches a lot..
On another note, Fox's Judge Napolitano turns out to be a classmate of Alito's.. and knows him "very well"..
Napolitano seems to be highly supportive of the nomination..
Not sure if that is good or bad at this juncture.
