Structural Barriers and State Election Rules
States set their own rules for registering and casting a ballot, and each extra step or deadline filters out some voters before they ever reach the booth. Those structural barriers, plus a person's own sense of political efficacy, explain most of the gap between who can vote and who does.
The Constitution leaves election administration mostly to the states, so the path from deciding to vote to having a ballot counted looks different depending on where you live. The typical steps are: register by some deadline, confirm your polling place, show up during open hours (or request a mail/absentee ballot), present whatever ID the state requires, cast the ballot, and have it verified and counted. Each step is a place where a voter can drop out of the process entirely.
Every rule change shifts the odds. A registration deadline a month before election day forces people to think about voting before campaigns usually catch their attention, so it quietly cuts turnout compared to same-day registration. Short poll hours or few early-voting days squeeze people with inflexible jobs or no transportation. Strict photo ID laws screen out voters, often poorer, older, or younger people, who are less likely to have the required documents. None of these rules bans anyone from voting outright, but stacked together they raise the cost of voting, and political scientists treat turnout as sensitive to exactly that cost.
Structural rules are not the whole story. Two people facing identical deadlines and ID laws can still make opposite choices, and that gap is where political efficacy comes in: the belief that your vote and participation actually change outcomes. Low efficacy, feeling like government won't respond no matter what, suppresses turnout even when access is easy. This sets up the next question in the unit: once someone does show up, the Electoral College and party competition shape how much their vote seems to matter.
