US: Pew Research Center analysis finds that Democrats and Republicans in Congress are now farther apart ideologically than at any time in the past 50 years. Republicans have moved further to the right than Democrats have to the left.

Can you clarify the metric(s) used for left/right?
(I'm not saying it's wrong, I'm just appealing for help because I've not grasped it yet.)

<<The Center’s analysis is based on DW-NOMINATE, a method that uses lawmakers’ roll-call votes to place them in a two-dimensional ideological space. It is designed to produce scores that are comparable across time. This analysis focuses on the first dimension, which is essentially the economic and governmental aspects of the familiar left-right spectrum and ranges from 1 (most conservative) to -1 (most liberal). >>
