If your concern is that Paul is at the top, and he is sometimes considered a libertarian, it has nothing to do with the list. Paul is at the top because he is up for reelection next year and has voted well. There is no intended manipulation.

Don’t you think it would make more sense to just list them from high to low in their ratings?
Do you really think that what readers take, or want from your list, is which names are in which future election cycle?
