Very interesting piece here.

Wish I knew more about the numbers it is drawn from. Assuming it is accurate then...

In a sample of almost 15,000 judicial votes, Republican-appointed judges gave liberal votes 38% of the time, while Democratic appointees gave liberal votes 51% of the time.

Would indicate that Democratic appointees are less biased than Republican appointees (another -invalid- assumption: the right percent to come us with is 50%). Except that when you put them on panels together with their ideological brethren (giving them the opportunity to commit "group-think")...

On an all-Democratic panel, Democratic judges vote in favor of affirmative action programs 85% of the time - on an all-Republican panel, Republican judges vote for affirmative action programs just 37% of the time.

the dems are considerably more biased.

And these are cool:

Would you guess that Democratic-appointed judges are more sympathetic to criminal defendants and more likely to rule in their favor? If so, you're wrong. On criminal appeals, Democratic appointees and Republican appointees vote alike. ["soft on crime" indictments are BS, then?]

and:

Would you guess that Republican-appointed judges are especially protective of property owners? Guess again. They're not.
