I doubt it would increase voting in states that already have an 14 days of early voting plus Election Day. In TN early voting includes Saturday's and some early evening hours and I think that gives everyone ample time to vote. There is also early voting by mail and it's a state law that employers give their employees time off to vote & they are not supposed to be required to use leave time. In addition it would mess up Super Tuesday's during a presidential election year. It gives the State more political power and influence to unite with multiple states for primaries. I'd rather see all states be mandated to have an early voting period. In TN that was very effective in raising voter turnout.
