Sen. Tom Coburn, Oklahoma Republican, said that 2013 may go down not only as the least productive ever in Washington but as “one of the worst for the republic.”

“In both the executive branch and Congress, Americans witnessed an unwinding of the country’s founding principles and of their government’s most basic responsibilities,” Mr. Coburn wrote in a Wall Street Journal piece posted Monday evening. “The rule of law gave way to the rule of rulers.”

Mr. Coburn cited the disastrous rollout of President Obama’s health care law and Mr. Obama’s “if you like your health care plan, you can keep it” promise, which the Tampa Bay Times‘ PolitiFact dubbed the “Lie of the Year.”

“The president apologized in part for his statements, but his actions reveal the extent to which he has conformed to, rather than challenged, the political culture that as a presidential candidate he vowed to reform,” Mr. Coburn wrote.
