Yes, but unfortunately, that is the only way anything is going to get done on this. The politicians represent the people. The people are going to have to do the heavy lifting. If the people demand action on abortion, the politicians will follow.
I actually give Romney high marks, even though I've always thought of him as a RINO. He's got a Clintonesque strategy in that Clinton spent years in Arkansas, and no one seemed to realize that he was a far leftwing nutcase. When he got into trouble in Washington, he morphed back into his prior disguise in order to prevent the GOP from beating him, but he remained at heart a liberal Democrat, and spent another 4 years impressing our government with the liberal image.
Romney might be doing the same thing, except in reverse. He may be trying to impress our government with a conservative image.
Of course, we don't really know which is the real Mitt Romney, and we may not unless and until he's President.
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.
