The New York Times opinion piece: Americans to Vote, or Else. 

The Left gets all worked up over voter integrity measures, deriding them as undue conditions on the right to vote.  However, refusing to vote or exercising the right not to vote can be equally seen as an expression of speech (unhappiness) and the freedom not to speak as a citizen.  Even the most prolific voter has walked into a polling place, looked at the ballot, and found themselves simply unable to cast a vote for any of candidates presented.

Would such requirements to vote make voting an undue condition of citizenship?
