the current field looks like they are contestants from a 1970's game show.

Slate:

In 2008, the so-called authenticity problem dogged him over his switchback positions on social issues such as abortion. Now it's health care. Where does the Mitt Romney who signed health care reform in Massachusetts with an individual mandate end, and where does the one denouncing President Obama's health care reform with an individual mandate begin?
--
Substantively, Romney was also confusing. When Romney makes the case for what worked in Massachusetts, the uninitiated are likely to wonder why such a success shouldn't be a national model—like the one President Obama signed. Democratic spokesman Brad Woodhouse joked in a tweet to his colleague Hari Sevugan "Romney is making a great case for national health reform. Book him on cable tonight?

As for Romney's speech, Ezra Klein shares some thoughts:

So Romney is also saying that it’s un-American for the federal government to pass and impose an individual mandate. A violation of the 10th Amendment, don’cha know. His problem, of course, is that he didn’t mention the 10th Amendment when he, like so many other Republicans, was praising, passing and selling both state-based and national individual mandates in the 1990s and early-aughts.

So how exactly is he going to sum this up for the Republican primary? “The individual mandate is great policy, but as president, I pledge to oppose it”? “I believe in states’ rights first and a functional health-insurance market second”? As for the rest of the speech, it was vague and contradictory in the same places as his op-ed, so my analysis from yesterday holds up.

Vote for me because I'll repeal something I believe and passed, but I only passed it because I used my constituents as lab rats like Doctor Moreau did to test it out on my state. I'd never do that to other subjects. Are you confused? So are Republican voters.
