Changing Sides in the Supreme Court

In the term just ending, is it true that the liberal justices voted as a bloc, while the conservatives often voted according to their judicial philosophy instead of their party interests? Yes, according to SCOTUSblog, but only if you're talking about the most important cases:

In the 26, a Justice on the left voted with the right a total of 3 times. In 2 cases, those votes determined the outcome and produced a more conservative result, because Justice Kennedy or one of the conservatives voted for the more liberal result.

In the 26, a Justice on the right voted with the left 14 times. In 6 cases, those votes determined the outcome and produced a more liberal result, because Justice Kennedy voted for the more conservative result.

I also considered the 10 cases I consider most significant. Of those, the left prevailed in 8. Those included the first 7 of the Term. (I mention the early cases to give a sense of how the results must have appeared inside the Court as the Term went along.) The right prevailed in 2, both in the final sitting of the Term.

In the 10, no Justice on the left voted with the right; the four Justices on the left voted together in every one of those cases. A Justice on the right voted with the left 4 times. Those votes determined the outcome in 2 cases, because Justice Kennedy voted for the more conservative result.
