No because the statistics are counted. People in the "smoke filled backrooms" pay attention to what third party messages are getting attention and in turn use that to inform how they change. Long term it isn't a bad strategy, but it does mean you have to accept whoever wins (though in rare cases a third party has won) for today. If one candidate isn't too bad I will vote for them.

In my case I've decided on criteria is has not held this office for more than one term (that is I give you two terms no matter what office you are running for) because no matter how much I agree with you I don't want anyone to spend too long in government.

The democrats have a bad record too. The record is bad in different areas, but both have plenty of reasons not to support them. You have to make a choice, (not voting is a choice) and there are not good ones, the question are any not so bad that you are willing to support them.
