I think this "did he march with Martin Luther King" story is
overplayed. It was wrong for Mitt Romney to imply that he had
witnessed something he had not. His phrasing did not sound like he
was speaking figuratively, if that was in fact his intent. Romney
does have a pattern of gilding the lily (although he isn't the only
Republican candidate to have that
problem).
That said, there do seem to be conflicting recollections about
whether George Romney marched with Martin Luther King Jr., as well
as conflicting sources. David Broder and Stephen Hess describe the
two men marching together in their book The Republican
Establishment: The Present and Future of the GOP, which was
published only four years after the Grosse Pointe march had taken
place. It doesn't appear that anyone came forward to dispute their
account at the time.
Based on various accounts, the most likely
scenario may be this: The two men both participated in major
Michigan civil rights marches within a few days of each other, King
in Detroit and George Romney in Grosse Pointe, and some people
honestly got mixed up. There were other ties between King and
Romney, and George Romney's stalwart civil rights record is
indisputable.
In any event, we should be careful before imputing bad motives
to anyone who thinks they remember the elder Romney marching with
King. Mitt Romney should be careful in describing events he did not
actually witness. And we should all be careful not to allow a minor
campaign kerfuffle detract from George Romney's true record.
