People are criticizing Sen. Rand Paul (R-Ky.) because he’s using his public service work providing free eye surgery in Guatemala as a campaign stunt [“An eye doctor’s 2016 vision,” front page, Aug. 22]. So what? Making service part of campaigning is a great idea. If just one-tenth of the time, energy and dollars used for political campaigns were directed to public service, imagine all the good it would do.

I disagree with Mr. Paul on nearly every issue, but I applaud his public service and hope this idea catches on and becomes the political equivalent of the ice bucket challenge.
