I will compute it for you. They have ALWAYS been that far left. They have just been faking any inkling to the right out of desperation to do ANYTHING to get votes. Easy calculation. I didn't even have to get out my calculus book and use differential equations, Bessel Functions, Legendre Polynomials, not to mention Conformal Mapping in the Complex Plane, to do it! LOL! :))
Oh, my. Waaay over my head. LOL
Upon reflection, you're probably right. Since they could never permit themselves to be called liberal, they had something to hide and I think what that was they were hiding was their deep distrust of the government (when run by Republicans) and absolute hatred of the country.
