Political ads often take what can generously be called interpretive liberties that bear only partial relation to factual accuracy. Even so, even campaign commercials rarely feature demonstrable, flat-out lies. That, though, is exactly what a new ad for former President Donald Trump does to Trump’s former U.N. ambassador, Nikki Haley.

Haley, alone among the serious Republican contenders for the presidency, has had the guts to tell the truth that the Social Security system faces insolvency within nine years and that, as a simple arithmetical fact, changes must be made to extend the system’s life span. Again, this isn’t opinion, it’s just math, as reported by the Social Security trustees themselves.
