Ezra Klein writes in the Washington Post that congressional Republicans have moved to the right on such issues as health care, stimulus spending, and a carbon tax, forcing Democrats to move to the center to find common ground. And thus:
If you imagine a policy spectrum that that goes from 1-10 in which 1 is the most liberal policy, 10 is the most conservative policy, and 5 is that middle zone that used to hold both moderate Democrats and Republicans, the basic shape of American politics today is that the Obama administration can and will get Democrats to agree to anything ranging from 1 to 7.5 and Republicans will reject anything that’s not an 8, 9, or 10. The result, as I’ve written before, is that President Obama’s record makes him look like a moderate Republicans from the late-90s.
His argument is that Mitt Romney and Newt Gingrich used to support "the basic architecture of the Affordable Care Act," John McCain (R-AZ) supported a cap-and-trade bill, George W. Bush pushed a stimulus bill in 2008—but now Republicans don't want to support any of those policies. So, he says, Democrats have moved to the right, away from what they really want, like single-payer health care, command-and-control environmental regulation, and no cuts to entitlements plus massive new spending. He says that leads to center-right policy.
But another way to look at it is this: on his scale of 1 to 10, where 1 represents bigger government and 10 represents smaller government, what's happening? Is government getting bigger or smaller? Take health care: if 1 represents national health care and 10 represents a free market in health care, then surely with income tax preferences for health insurance, Medicare, the prescription drug benefit, and government paying for more than half of all health care, we were at least at 5 by 2009. Everybody from Michael Cannon to Joe Biden thinks Obamacare is a BFD on the road to total government control of medicine. So let's say it put us at 3 or 4.
You can see the same pattern in the other issues Klein discusses. Carbon tax, cap and trade, stimulus spending—they all make government bigger than it is now. So when Republicans endorse any of those policies, they are playing on bigger-government territory. Now, Republicans say they're not going to do that any more. So Klein's complaint is not really that Republicans are insisting on "8, 9, or 10" policies; they're just no longer proposing policies in the 3 and 4 range, hoping that Democrats will agree to make government only a little bigger, rather than way bigger. Sounds like maybe the debate is moving back toward the 50-yard line, instead of taking place entirely in Democratic territory.
Note: Klein talked only about economic issues, so I've done the same. There's a clear trend in a liberal/libertarian direction on social issues such as marriage and marijuana. And Republicans who propose further restricting immigration or getting involved in yet another Mideast war are hardly advocates of small government. This analysis deals only with fiscal, regulatory, and entitlements issues.
