Where can your vote go? To that Candidate who best reflects your individual beliefs.
Historically, I have split my vote between the "Libertarians" and the "Republicans"... based purely on who best represented my views. Party label is completely irrelevant to me -- I only care about who best represents my beliefs.
After all, Elections are won by Thousands (state) or Millions (federal) of Votes. I only have One little vote for each Candidate listed -- my own.
I am certainly not going to waste my vote by assigning it to someone I don't believe in. Given that my vote "counts" for maybe one-millionth of an electoral decision, I am going to assign my vote to the candidate who most closely represents my little portion of the ideological spectrum. At least let the "powers that be" know where I stand, one-millionth of a point at a time.
