How can we trust a liar as big as John McCain?

I'm using the L-word. So that may come across as a slashing blog remark.

But let's slow down and look at the facts that are not being disputed. John McCain is telling lie after lie. Not off the cuff remarks that can be excused as accidents or flubs but the same lies consistently and many of them. Serial liars are never trustworthy people -- that is a truism. But it also demonstrates a deeper character flaw. A normal job applicant would be disregarded out of hand after such a record became clear.
