Why would a liberal vote for Hillary vrs Obama?

Im a Libertarian but I do not understand why a real, 100% legit Liberal Democrat, or just a Liberal in general, would vote for Hillary over Obama.

I mean im a Libertarian and even I can see that Obama is less of a Washington criminal, less of an establishment fiend than her. I just cannot see how liberals could truly sleep at night knowing that they supported a Washington, 20+ years politician, establishment liberal over a fresh, true, un-bought liberal such as Obama.

Here's why I think you liberals should put you're support behind Obama 100%, and abandon Hillary altogether. Im a Libertarian, and I am willing to vote for Obama. Now if im a Libertarian,which is essentially a radical Republican in some respects, and im so excited for Obama that I would vote for him if he was the nominee verses the fake whom is Mccain, then what does that tell you libs about Obama's centrist appeal?

Let me say, I would never vote for Hillary, and I know many, many conservatives, a good 50+, who would not dare vote Democratic if the nominee was Hillary. BUT I have spoken to many of them and asked them, would you vote for Obama if he made it? Almost all said yes they would. So I think you really should all drop ur support for Hillary and help Obama, because if he can excite the people im talking about into voting for him, and their some pretty staunch conservatives, then I would say he's the best bet for the Democrats.
