DeMint's Fiscal Fundamentalism

Daniel Larison says I'm wrong to call Mitch McConnell  the "most rightwing of Republicans." What about DeMint?

While I can understand opposing the deal, DeMint and the Club are in error in their resistance to the deal when they insist that all of the tax cuts be made permanent. The absolutist rejection of the estate tax compromise is also foolish, since the 35%/$5 million exemption arrangement is probably the best that can be had. For the sake of adding hundreds of billions more in debt, DeMint appears to be prepared to try to kill the deal. It’s important to note here that if DeMint succeeds, it will be in the name of even greater fiscal irresponsibility.
