Despite sometimes taking years to develop and write, 1,829 federal regulations on programs including Obamacare and Dodd-Frank had to be corrected since 2001, with the Obama administration reaching its high last year with a 4.1 correction rate, according to a new analysis.

The American Action Network, a center-right policy institute led by Douglas Holtz-Eakin, former director of the Congressional Budget Office, reviewed every regulatory correction and found that one of 30 regulations has been corrected.
