State governments have long been accused of backroom dealing, cozy relationships with moneyed lobbyists, and disconnection from ordinary citizens. A new study suggests those accusations barely scratch the surface.

The study, issued Monday by a consortium led by the Center for Public Integrity, a nonpartisan watchdog group, found that most states shy away from public scrutiny, fail to enact or enforce ethics laws, and allow corporations and the wealthy a dominant voice in elections and policy decisions. The study gave virtually every state a mediocre to poor grade on a wide range of government conduct, including ethics enforcement, transparency, auditing and campaign finance reform. No state got an A; five received B’s, and the rest grades of C, D or F.

For all the reform talk by many governors and state lawmakers, very little has really changed in most capitals over the decades. Budgeting is still done behind closed doors, and spending decisions are revealed to the public at the last minute. Ethics panels do not bother to meet, or never enforce the conflict-of-interest laws that are on the books. Lobbyists have free access to elected officials, plying them with gifts or big campaign contributions. Open-records acts are shot through with loopholes.

And yet all the Republican presidential candidates think it would be a good idea to hand some of Washington’s most important programs to state governments, which so often combine corruptibility with incompetence. In a speech on Monday, Mitt Romney said he would dump onto the states most federal anti-poverty programs, including Medicaid, food stamps and housing assistance, because states know best what their local needs are.
