Ahem, knowing a candidate's voting history shows what kind of decisions he (or, realistically, his paymasters) has made in the past;
- If consistent, it gives a clue as to where his heart (or rather, purse) is, and where he's likely to be in the future.
- If inconsistent, take another look. He may well be a flip-flop, but he may also have reconsidered the political terrain as it changes. Or he changed sponsor. It's which it is, that decides how trustworthy he's likely to be.
