This just dropped into my inbox from the former Speaker:

I Signed the Pledge To Repeal Obamacare, Have You? by Newt Gingrich
Yesterday in Mason City, Iowa, I signed the Obamacare Repeal Pledge, sponsored by the Independent Women’s Voice and American Majority Action.
Obamacare is such a massive and complex power grab of a law that there are countless specific reasons to oppose the law.
But as I was signing the repeal pledge, I reflected upon three big reasons that Obamacare must be repealed:
It’s Unconstitutional. Period.
As Virginia Attorney General Ken Cuccinelli has argued, if the federal government has the power to force you to purchase a product or service, there is no end to its power.
As I argue in my forthcoming book, A Nation Like No Other: Why American Exceptionalism Matters and show in Callista’s and my documentary, A City Upon a Hill: The Spirit of American Exceptionalism, Obamacare’s mandate to purchase health insurance is an assault on our country’s founding principles of limited, clearly delineated federal powers and an erosion of the rule of law.
Article 1, Section 8 of the Constitution clearly spells out the powers of the federal government. When the Democratic Congress passed Obamacare, the bill’s supporters argued that the individual mandate was constitutionally justified under the Commerce Clause, a provision that gives Congress the power to “regulate Commerce…among the several States.”

Honestly. I don’t know if this is a tease to buy his book, watch his documentary, or get on board his campaign.
