Those guys?

IT SEEMS that there are liberal Republicans after all. Or at least, the adjective is used when describing members of the party of Lincoln. Examples cited are Arnold in California and Bloomberg in New York. But really this just makes my point, both are Republicans only because they concluded correctly at the time that they couldn't win a Democratic primary and ran as Republicans. The better and more accurate modifier is RHINO or Republicans in name only. Nevertheless, why a self-described liberal would register as a Republican mystifies me.
