Spurgeon's Choosing Between Two Evils

People have been quoting Spurgeon's quote about 'not choosing between two evils' as if Spurgeon had this coming election in mind. But even if he had, doesn't it present a problem for could it not be said that we are always choosing a lesser 'evil'.  What of a choice between a business man who ran a casino (for the record I'm not a fan of casinos) and a Josef Mengele? Should one still sit out the election because both were deemed 'evil'? I believe Christian theology continues to make the point that no one is good (apart from God's grace) let alone perfect. We are all fallen. So my fellow citizens, we are not electing a pope. As a matter of fact, has there ever been a president who was free from all sin? The point is: which candidate has more potential to do insidious evil and which has at least some potential for good? I think Spurgeon would cast his vote.
