This is a bizarre time in U.S. presidential politics. American voters are faced with an unsavory choice between two presidential candidates, neither of whom would be viable if the other party offered a credible alternative.

Some of these Nader voters now work for the Democratic Party -- and deeply regret their 2000 vote.

While it is easy to understand the reasons that some people might be inclined to choose a "protest" vote -- or decide to sit on their hands -- the fact is that either of these actions will have one and only one result: putting Donald Trump into the White House.

Trying for a "perfect" candidate can be a disaster; we may end up with someone diametrically opposed to our values.
