Establish Federal Standards Allowing All Citizens to Vote by Mail or Online, For Three Weeks Prior to National Elections

Currently, states are allowed to manipulate voting access through subtle and not-so-subtle means, thus disenfranchising portions of the electorate. Requiring all states to allow early voting, vote-by-mail, and even online voting would level the playing field. This should become federal law (or Executive order) which requires such methods for a minimum of three weeks prior to any national election (Senate, House, or President), thus maximizing voter turnout. Weekend voting must be included along with in-person options for early voting.
