According to on the issues - John McCain is way right of this guy. But I don’t know why they would call McCain in the right conservative section.
I would encourage everyone to take the test at the bottom of the link http://www.ontheissues.org/john_mccain.htm
I am right but more toward the libertarian than either McCain or Palin.
The part they show as “populist” they used to show as “statist” which I thought was more descriptive.
I've found that On the Issues has some odds ways of tabulating their assessments. I don't really trust the site, and haven't used it for months. Regardless of who the politician is, OtI is the last place I'd go to get info about them.
