Who was the most important legal philosopher of the 20th-Century

I've been having fun with (utterly unscientific and unreliable) polls on my other blogs, so here's one for this audience.   Maybe we'll have a run-off, depending on the results here.  Feel free to post omissions from the list below in the comments.

	Joel Feinberg
	John Finnis
	Lon Fuller
	H.L.A. Hart
	Hans Kelsen
	Karl Llewellyn

UPDATE (MARCH 4, 7 PM CST):  Here are the results after 70 votes:

1.  H.L.A. Hart (59%)

2.  Joseph Raz (13%)

3.  Ronald Dworkin (9%)

4.  John Finnis (6%)

4.  Hans Kelsen (6%)

6.  None of the choices offered--someone else (4%)

7.  Lon Fuller (3%)

8.  Karl Llewellyn (1%)

By the way, I didn't vote for Llewellyn, I voted for Hart.  Much as I enjoy Llewellyn, he's not, needless to say, a good philosopher (though not obviously worse than Fuller!).  Obviously the Anglophone readership explains how Kelsen could come in behind Dworkin.   I'll do another tally in a few days.

UPDATE (MARCH 7 6 PM CST):  So with not quite 140 votes cast, here's my final tally:

1.  H.L.A. Hart (55%)

2.  Hans Kelsen (14%)

3.  Joseph Raz (11%)

4.  Ronald Dworkin (9%)

5.  John Finnis (5%)

6.  Someone not listed as a choice (3%)

7.  Lon Fuller (2%)

8.  Karl Llewellyn (1%)

8.  Alf Ross (1%)
