Why is voting day on a Tuesday?
Election Day (United States)
In Colorado, Oregon and Washington State all major elections are by postal voting, with ballot papers sent to voters several weeks before Election Day.[14] In Colorado and Oregon, all postal votes must be received by a set time on Election Day, as is common with absentee ballots in most states (except overseas military ballots, which receive more time by federal law). Washington State requires postal votes be postmarked by Election Day. For the 2008 presidential election, 32% of votes were early votes.[15]
