The complaint that I was expressing in the post about the Roberts Court was the deep suspicion that I have that while conservatives believe that they are voting in accordance with conservative principles, but the actual practice of conservative political leaders suggests that they subscribe to a "cafeteria conservatism" that will act on conservative principle when it suits the needs of big corporate interests to act on conservative principles, but will sell out those principles in an instant if corporate profits are endangered. Faced with the prospect of ObamaCare, the minions of the insurance companies fight tooth and nail against Socialism. But when Hank Paulson says that banks need a bailout, they take up the hammer and sickle and give Goldman Sachs what it wants.
It seems to be a notorious fact about Republican leaders that, although they believe in cutting taxes and cutting expenditures, they have a far easier time gettiing the tax cuts done than they have getting the expenditure cuts done.
I'm sure if liberals get to spend as much time in political power as conservatives have, we will see how the political process undercuts liberal principles.
