I doubt it. Very few Democrats call themselves liberals, even those who ARE liberals.
I once again agree with my good friend from Pennsylvania on here. I, too, doubt any of the potential 2016 Democratic candidates would even call themselves a liberal if they were asked in a debate. Give them credit, Republicans have successfully demonized the word liberal, which is somewhat ironic seeing as how liberal is only two letters short of liberty, and liberty is what the Republican/Tea Party allegedly stands for.
