it'd be nice if you didn't try and pass off over-simplifications as fact.
We have a parliamentary system which is based on the electorate voting for the candidates and political parties who's policies they most agree with to represent them in parliament, that is "a fact".
Individuals might vote in a certain way for all manner of reasons, including because a candidate has perhaps a nice pair of large knockers or an amusing mop of unkempt blond hair, but the electorate as a whole does not.
And yes, on occasions some people will not always vote for their first preferred choice if they feel they stand little chance of winning, and instead go for their second choice. Some electoral procedures such as French general elections actually help to give people a second choice if their first choice is eliminated.
Whatever the system it is designed to allow the electorate to choose those who's policies they most agree with to represent them in parliament, even if they are given a second choice or some individuals decide to vote for the most handsome candidate.
That is the whole basis of our parliamentary system and there is nothing "ridiculous" about it.
