It's perfectly possible that Loon Lake isn't a very large place. :^) Regardless, the fact that Brainless Joe is going to every nook and cranny means, he knows how to campaign and is willing to do it. Primary voters will remember that, and him, and remember the "top tier" candidates who didn't bother.
And Hillary did her “tour” using a an airplane (to fly her and her top staff between cities) and a well-publicized black van (to carry the low-lifes, and their press corpse following behind)
Biden, I will admit, is actually campaigning in the places where people live and vote in these two small states: Vermont-er-New Hampshire and Kansas. The rest? Campaigning in front of their press corpse in New York, Chicago, and Washington DC.
