How do you write a platform for a party whose candidate's positions span the unfortunate gamut from nonexistent to offensive to flatly at odds with those of the party?
Such is the thankless task consigned this year to Sen. John Barrasso. The Wyoming Republican is a Yale-trained orthopedist with a voracious appetite for history (he's currently immersed in a Ulysses S. Grant biography) and a political junkie's love of game and country (Barrasso hasn't missed an inauguration since his father, a Pennsylvania cement finisher, took him to John F. Kennedy's).
Barrasso exhibits a wonk's inclination for policy specifics (he just hosted surgeon and writer Atul Gawande to speak to fellow senators on health care) that puts him more in the "sweat the details" spirit of Hillary Clinton than the details-shmetails approach of Donald Trump.
Barrasso is, in short, the anti-Trump. Not in the sense of being opposed to the nominee -- he isn't, although, like most of his GOP Senate colleagues, he scarcely exudes enthusiasm for Trump.
