Bob Dole talks trash, can't back it up

Bob Dole opens his mouth and inserts his foot. On Sunday he said:

Dole added: "And here's, you know, a good guy, a good friend. I respect his record. But three Purple Hearts and never bled that I know of. I mean, they're all superficial wounds. Three Purple Hearts and you're out."

And then there's this bit from a 1996 Nation article that excerpts his autobiography:

It was in the first of these night patrols that Dole received the wound for which he was awarded his first Purple Heart. He ruefully confesses in his 1988 autobiography that his wound was self-inflicted: "As we approached the enemy, there was a brief exchange of gunfire. I took a grenade in hand, pulled the pin, and tossed it in the direction of the farmhouse. It wasn't a very good pitch (remember, I was used to catching passes, not throwing them). In the darkness, the grenade must have struck a tree and bounced off. It exploded nearby, sending a sliver of metal into my leg -- the sort of injury the Army patched up with Mercurochrome and a Purple Heart."
