The prospective candidates would go from town committee to town committee not solely to deliver their intra-party stump speech, but to learn of other candidates running for local office that year, and would lend them whatever celebrity they might possess as well as other intangible assets they might have acquired to help those locals win their respective races.
It made sense, it's better to have a few Selectmen or Town Council members in your corner than not. Besides, successful local campaigns are rarely won alone, and political alliances being what they are, the savvy higher office candidate could well be seen by winning office holders and their entire teams in several communities, as an asset.
Knowing the locals who serve the behind the counter in countless coffee shops, or as youth sports coaches, and so forth can't possibly hurt either.
Then the folks with the big checkbooks arrived!

Here's a run down of the contributions to town committees made by just two candidates lately.
