That site is somewhat out of date as the Reform and Natural Law parties have imploded (altho the Reform party might be able to emulate the phoenix) Also, its questions don't measure the intensity of feeling on a particular issue.
And some of the questions are two-parts such as:
Increase/maintain/decrease
taxes on gifts and inherited wealth I'd increase inheritance taxes and decrease taxes on winnings (i.e. lottery).
My results are:
1) Green Party 93%
2) Democratic Party 71%
3) Natural Law Party 71%
4) Reform Party 50%
5) Libertarian Party 43%
6) Republican Party 21%
7) Constitution Party 14%
