NPR reports that more than halfway through the primary elections, the map of competitive Senate races is coming into focus — though, as the piece notes, several races remain unsettled. Both parties, we are told, see a credible path to winning the chamber. That is healthy. A republic without genuine contest is a republic already half-asleep.

I spent years as postmaster because I understood that self-government is only as good as the information that feeds it. The postal road was, in its day, the nervous system of the nation: carry the gazettes cheaply and promptly, and the citizen can reason; choke the flow, and he is left to rumor and faction. Today the platform has changed — the mail coach is now a fiber-optic cable — but the principle holds exactly. If the voter cannot get reliable intelligence about who is running, on what terms, and with what record, the ballot becomes a guess rather than a judgment.

Here is the practical concern I would press on any working person watching these races: the Senate controls the public purse in ways the average household feels directly. Tariff rates, the terms on which the government borrows, the rules governing the banks that hold your savings — all pass through that chamber. When I wrote of paper money in colonial Pennsylvania, my argument was simple: money badly secured is a slow tax on those who hold it. A Senate majority that writes careless fiscal law is doing the same injury by a longer route.

I would also counsel against the temptation to treat a competitive map as a spectacle rather than a responsibility. The NPR account lists races that remain genuinely open (inference: as is typical at this stage of a cycle). That openness is an invitation, not merely a curiosity. The citizen who studies the candidates — their positions on debt, on the cost of credit, on the rules of commerce — and then votes on the strength of that study is doing exactly what the republic requires of him or her. The citizen who watches the coverage as entertainment and then stays home is wasting the franchise others worked hard to secure.

A word on civic self-improvement, which I confess was always my favorite subject: between now and November, a person of ordinary industry can read each candidate's stated position on one or two questions that touch her own household — the cost of borrowing, the stability of the currency, the terms of trade. That is not a heavy burden. I once taught myself to read French by sitting with a book and a candle after the print shop closed. An hour a week on a Senate race is well within the reach of any person who is serious about being free.

The counsel I leave you: pick one contested race that will affect your state or your pocketbook, learn what each candidate actually proposes on a single financial question, and carry that knowledge to the ballot. A republic is not maintained by passion alone; it runs, like a good shop, on accurate information and steady habits.
