Actually, if you change the "select only candidates who" by unchecking the two boxes that have already been checked off for you (but not the third one, why is that?), and then answer those NAACP, League of Conservation Voters & ACLU questions as someone you are aligned with, or whatever, it changes the outcome a bit.
I decided my second time through (when no Green candidate came up for me, but a Green candidate won't register if you don't deselect those two boxes before you do the test), that I would answer that way, even though I'm not real crazy about the League of Conservation Voters (much too conservative for my tastes) and the NAACP (much too conservative and reactionary for my tastes) I did check that the candidate I supported would have to support them, or whatever, the Bush score dropped, the Green option showed up, and several other interesting things happened.
But the 0% for La Rouche didn't change. Or the Constitution Party candidate either!
