A Times news article from Chicago begins:
With the selection of a multimillionaire businessman to be the Republican candidate for governor in Illinois, union leaders have begun bracing for one of their starkest campaign battles of the year over the fate of public sector labor unions, pensions and pay.
The same article mentions President Obama but doesn't call him a multimillionaire, even though he is one. And the Times writes about Mayor de Blasio all the time without calling him a multimillionaire, even though he reportedly owns "a pair of two-family homes on 11th Street in Park Slope that are valued at more than $1.1 million apiece."
The first quote in the Times article comes not from the Republican candidate but from a labor leader, Roberta Lynch of the American Federation of State, County, and Municipal Employees. The Times writes about her without saying how much money she has or makes, even though that information is readily available from the U.S. Department of Labor website and indicates she earned $140,834 from the state union in 2013. The judgment seems to be that a person's personal wealth is worth mentioning prominently in the news article so long as the person is a Republican politician.
