Clinton's not a far-left nutcase. He's been fairly liberal in his inclinations and political positions, but to be 'far-left' implies some personal commitment to the cause that simply isn't there. Clinton is committed only to himself, not to any ideology. He doesn't care that much about policies, as long as he's getting glory and praise. If Republicans had been in control of Arkansas in the 1970s & 80s, then he'd probably be one.
Hillary, on the other hand, is actually liberal, though she has also picked up Bill's vain powerlust that allows her to compromise her liberal principles when she thinks it's to her advantage.
Anyone who proposes to socialize the healthcare industry is a far left nutcase. The fact that he backs off when he sees the writing on the wall doesn't persuade me otherwise.
