I don't have any reason to examine your voting habits, personally :-)
On the other hand, I do have a reason to examine the voting habits of a politician, especially one who is supposed to be "representing" me and my peers.
My vote-casting decision is supposed to be a measure of how much I trust the candidate to vote in ways that I would approve of, as I am barred by "democracy" from voting on everything (on the other hand, a free referendum on every issue would be impossible in the current technological/political/social climate).
You are free to vote arbitrarily on K5, voting just for your own personal amusement and personal interest in (your personal idea of) K5 itself. A politician should not be free to vote arbitrarily (although they are free-willed), and I like mechanisms that allow me to be informed.
Another thread would be that old favourite, the value of uninformed voting. And yet another would be the value of allowing un-related riders on bills.
