I was wondering that, since it told us in an article subhead, and then in the article itself, that Republicans have “concerns” about federal spending. In the article, the concern was over “excessive” federal spending.
Unless the Washington Post’s reporters are mind readers, they have no idea what Republicans are actually concerned about. Republican politicians, even more so than Democratic politicians, have also demonstrated an extraordinary ability to say things that are not true, so there is basically zero reason to believe that what they claim to be their concerns are their actual concerns.
The way this should be reported is simply to tell readers what the Republicans say, for example refer to “complaints,” rather than try to tell us what they think.
