It's also possible that someone who lies 99% of the time has something really important to say with the other 1% (if you can even separate it from the 99%), but I wouldn't consider that person trustworthy or even worth dealing with.

Not saying that perfectly describes Walker, but the evidence does seem to point in that direction.

If you still want to trust someone like that, I guess that's your prerogative, but... well, that sort of thing doesn't seem like a winning strategy in life.
