I think a lot of people assume that digital voting will obviously lead to re-enfranchisement of certain groups and better turn out from other groups of potential voters. It's a noble goal, but dangerous to assume that outcome is likely.
I'm all for easier access to the polls. I've heard great things about Oregon and a few other states that make broad use of vote-by-mail (with a paper ballot). Yes, that has it's own issues, but my understanding is those issues pale in comparison to the upside of easy access. Failing that, I'd love to see voting day made a holiday or moved to a weekend.
And I loathe efforts from certain groups within the US to make voting more difficult. Removing polling places, reduced hours, voter ID laws (lacking substantial proof that fraud is a problem).
