There is no such thing as a wasted vote if you vote for the candidate that most closely reflects your views.
The only vote wasted is the vote not cast.
That is true in theory but not in principle. However, a change is called for when pluralities rather than majorities elect Presidents. I favor third parties and run-off presidential elections. Without run-off elections, Ralph Nader, or any third party, has little chance.
Imagine Republican candidate Bush, Democrat candidate Kerry, and third party candidate Nader running for president. Excluding Candidate Nader from participating in the presidential debates denies American voters hearing one of the candidates’ points of view. To compound the sanctimony the leading candidates tell the citizens that voting for Nader is a wasted vote.
However, consider the same scenario if no candidate received a majority vote and there were a run-off election between the two candidates receiving the most votes. Ralph Nader may not be one of those two but under these circumstances, all citizens could have truly voted their conscience without fear of wasting their vote.
