Non sequitur. “Critics point to Santorum’s Senate votes against a National Right to Work Act, in favor of Davis-Bacon wage rates, and in favor of raising the minimum wage to show that Santorum was overtly pro-union. But in his speech to the Detroit Economic Club Thursday afternoon, Santorum had an answer ready when asked how he would handle organized labor as president. ‘I’ve been attacked as the ‘big union’ Republican in this race,” Santorum said. “I went back to look at my AFL-CIO scorecard, and I had a 13 percent rating.’” But what’s his excuse for those votes?

Nonsensically, VP Joe Biden claims the stimulus worked.

The non-partisan Congressional Budget Office says it hasn’t. “The rate of unemployment in the United States has exceeded 8 percent since February 2009, making the past three years the longest stretch of high unemployment in this country since the Great Depression. Moreover, the Congressional Budget Office (CBO) projects that the unemployment rate will remain above 8 percent until 2014. The official unemployment rate excludes those individuals who would like to work but have not searched for a job in the past four weeks as well as those who are working part-time but would prefer full-time work; if those people were counted among the unemployed, the unemployment rate in January 2012 would have been about 15 percent. Compounding the problem of high unemployment, the share of unemployed people looking for work for more than six months — referred to as the long-term unemployed — topped 40 percent in December 2009 for the first time since 1948, when such data began to be collected; it has remained above that level ever since.”

Noncompliance, at last, with the media debate demands. “CNN Cancels March 1 Debate After Candidates Decline.”

Non-professional political players, especially millionaire donors, should be wary when going on TV. (No wonder Sheldon Adelson is never heard from.) “Billionaire Santorum backer: In my day, contraception was women putting aspirin between their knees.”

Non-panicked (contrary to pundits invitations to set his hair on fire), Romney says a loss in Michigan is not happening.

Non-serious? “Rick Santorum warned a quiet North Dakota audience Wednesday that their state’s booming oil industry positioned the region as a prime target for terrorism.” No, apparently he meant it.

Noncandidates can still be powerful critics. “Sen. Marco Rubio isn’t waiting for a vice presidential offer to go after President Barack Obama: He’s been locked in a quiet battle with the White House for months, blocking key diplomatic appointments in hopes of getting his say on foreign policy.”
