Sen. Jim DeMint (R‑SC) has been a leader in the fight for fiscal responsibility in Congress. He’s even led on issues that many elected officials have shied away from, such as Social Security reform and free trade. Recently he said that he would support Pat Toomey over Arlen Specter in a Republican primary, which may have prompted Specter’s party switch. DeMint was widely quoted as saying, “I would rather have 30 Republicans in the Senate who really believe in principles of limited government, free markets, free people, than to have 60 that don’t have a set of beliefs.”

It may have been feedback from that comment that caused DeMint to write an op-ed in the Wall Street Journal on his vision of a “Big Tent” Republican party. He makes some excellent points:

But big tents need strong poles, and the strongest pole of our party — the organizing principle and the crucial alternative to the Democrats — must be freedom. The federal government is too big, takes too much of our money, and makes too many of our decisions.…

We can argue about how to rein in the federal Leviathan; but we should agree that centralized government infringes on individual liberty and that problems are best solved by the people or the government closest to them.

Moderate and liberal Republicans who think a South Carolina conservative like me has too much influence are right! I don’t want to make decisions for them. That’s why I’m working to reduce Washington’s grip on our lives and devolve power to the states, communities and individuals, so that Northeastern Republicans, Western Republicans, Southern Republicans, and Midwestern Republicans can define their own brands of Republicanism. It’s the Democrats who want to impose a rigid, uniform agenda on all Americans. Freedom Republicanism is about choice — in education, health care, energy and more. It’s OK if those choices look different in South Carolina, Maine and California.

That’s a good federalist, or libertarian, or traditional American conservative vision. But is it really Jim DeMint’s vision?

DeMint says “that centralized government infringes on individual liberty and that problems are best solved by the people or the government closest to them.” And he says it’s OK if “choices look different in South Carolina, Maine and California.” But marriage is traditionally a matter for the states to decide. Some states allow first cousins to marry, others don’t. Some states recognized interracial marriage in the early 20th century, others didn’t. And in every case the federal government accepted each state’s rules; if you had a marriage license from one of the states, the federal government considered you married. But Senator DeMint has twice voted for a constitutional amendment to overrule the states’ power to grant marriage licenses to same-sex couples. In his op-ed, he writes, “Republicans can welcome a vigorous debate about legalized abortion or same-sex marriage; but we should be able to agree that social policies should be set through a democratic process, not by unelected judges.” That’s a reasonable argument, but the amendment that DeMint voted for would overturn state legislative decisions as well as judicial decisions.

Does Jim DeMint believe that “it’s OK if choices [about marriage] look different in South Carolina, Maine, [Vermont, New Hampshire], and California”? If so, he should renounce his support for the anti-federalist federal marriage amendment. If not, then it seems that he opposes the Democrats’ attempts to “impose a rigid, uniform agenda on all Americans … in education, health care, energy and more,” but he has no problem with Republicans imposing their own “rigid, uniform agenda on all Americans” from South Carolina to Vermont.

It might be noted that Senator DeMint also supported the federal attempt to overturn Florida court decisions regarding Terri Schiavo, but we can hope all Republicans have learned their lesson on that bit of mass hysteria.
