Can someone explain these contradictions?

Conservative Christians who tell me they believe the Bible tell me that this story is true:

He looked up and saw the rich putting their gifts into the treasury; 2 and he saw a poor widow put in two copper coins. 3 And he said, “Truly I tell you, this poor widow has put in more than all of them; 4 for they all contributed out of their abundance, but she out of her poverty put in all the living that she had.” (Luke 21:1-4)

Then they tell me that my one puny protest vote for a third party candidate who does not advocate intrinsic grave evil is absolutely worthless and meaningless.

Then they tell me that my absolutely worthless and meaningless vote IS ENORMOUSLY MEANINGFUL BECAUSE I AM HELPING THE OTHER GUY, BE AFRAID BE VERY AFRAID!!!!

Personally, I suspect these contradictions, being true contradictions, can’t be reconciled because they are at variance with reality.  But I think my position can be easily reconciled with reality.  It’s this: You matter.  Your vote, no matter how statistically insignificant matters, because you matter.  You may not matter to powerful men and your vote may not have a statistically significant impact on an election just as the widow’s mite had no statistically significant impact on the economy of the Roman Empire. But she mattered and even her tiniest choices mattered to God because she mattered.  You and your seemingly insignificant vote matter too.  Think about your vote that way.  Use it for good and not to support grave intrinsic evil.
