"Answer the following questions and we'll match your results to the (remaining) 2012 Presidential election candidates." 22 weighted questions.
This isn't going to change anyone's mind but there might be a small surprise or two regarding relative preferences. My results gave Romney and the Republican Party a higher percentage than I would have for instance but agreeing with Obama and the Democratic party about 40% of the time seemed about right.
Not to be shy; my scores:
Paul 89, Romney 82, Gingrich 51, Obama 40
Libertarian 85, Republican 72, Democratic 40, Green 30
