. . . all of which simply is a illustration of the fact that some excellences are uncorrelated with others. Even in the world of athletics, a good baseball pitcher is almost never a good baseball hitter (at the professional level). And that is becase if you're a good pitcher you can make the bigs whether or not you can hit--whereas even the finest-fielding shortstop or second-baseman won't make the majors without some facility with the lumber.A pitcher, if he's sensible, hopes only to come to bat with no one on and two outs, so nobody's particularly sorry when he makes an out and goes out to the mound to do what he's actually competent at. A high-school dropout celebrity would be well advised to consider an opportunity to opine on world events as an opportunity to make a fool of herself, and just pass. I suppose it shouldn't be surprising that those who lack the prudence to pass on that, also lack the prudence to have a considered conservative opinion on much of anything.
