Are convenience voters—those who cast their ballots early in-person or by absentee mail—less politically knowledgeable than those who wait until Election Day to vote? Conservative pundits, state lawmakers, and even President Donald Trump have expressed concerns about convenience voting, claiming that early voters are less politically knowledgeable, and thus more likely to cast uninformed ballots. More recently, North Carolina lawmakers introduced a bill that would eliminate early voting on the last Saturday before Election Day. Theoretically, based on what scholars know about convenience voters, there is good reason to expect that politically knowledgeable voters are more likely to vote early than on Election Day. Drawing on five Cooperative Congressional Election Study (CCES) national pre- and post-election surveys and data from an original survey of Florida registered voters conducted in 2017, we asses whether less politically knowledgeable voters are more likely to vote early in-person or by absentee mail rather than wait until Election Day to cast their ballots. Our multinomial logistic regression models with fixed-effects for those states permitting convenience voting, and controlling for standard socio-economic, political, and campaign effects, find no evidence to support the claim that less politically knowledgeable voters are more likely to cast their ballots before Election Day.
