John McCain memorably called himself “a foot soldier in the Reagan revolution.” I count myself as a foot soldier, too. I have walked precincts in every election, save one, since 1968. And, as an historical researcher, I have studied every presidential election since 1788. In the last six months of this election year, I logged some 13,341 miles on the Family Research Council-Heritage Foundation’s “Values Bus” to some 40 cities and towns in eight states. Campaigning at the grassroots level, you learn stuff.
