Thanks for the reply. Your points are well taken. Having some tangible record of voting would indeed be an enormous benefit of the current system; coincidentally all of the things that make it unwieldy are also functions of it's tangibility :/.
Overall I would tend to agree with you, however it's worth pointing out that voting on your tax return violates both the anonymous vote (offhand I can't find where that guaranteed), and infringes on the rights of many legally qualified voters as prescribed by Amendment 14
, Section 2 of the Constitution: the right of any voter shall not be "... in any way abridged, except for participation in rebellion, or other crime..." etc., etc.. As you say, voting on your tax return would tend to exclude many people. If we're going to start infringing on people's rights to vote, I propose that we start with a basic civics test, mandatory with every ballot cast; anyone scoring below 85% has their votes automatically piped to /dev/null (or /dev/landfill, if we're still using paper ballots).
And no, I don't own 27 pairs of sweatpants.
