That's a dumb quiz. It had Kucinich as my number 1 choice, and I pretty much disagree with all of his actual positions.
It had me agreeing with him on taxes - but the only tax question was the one on whether the 2001 and 2003 tax cuts should be made permanent. Which is dumb, b/c I don't think any tax policy should be permanent, it should depend on various factors... but I supported the 2001 tax cut at the time, and still think it was the right move at that time. I also would rather not have any current tax policy be permanent, b/c I think the current tax structure itself should be overhauled. Ugh. What a ridiculous quiz.
