"Since 1967, there have been at least three different accounts of the injuries that purportedly earned Murtha his Purple Hearts.
Those accounts also appear to conflict with the limited military records that are available, and Murtha has thus far refused to release his own military records."

So Murtha litterally is just a fatter older less charismatic version of John Effing Kerry. No difference in them at all.
