GRAND RAPIDS, Mich. – We reached an American landmark Friday that will be noted by few and celebrated by none. It is the 40th anniversary of the confirmation of Gerald R. Ford as vice president.On the surface there's little reason to mark the ascension of anyone to a position that John Adams, the first man to occupy the vice presidency, described with some accuracy as "the most insignificant office that ever the invention of man contrived." There have been 47 vice presidents, and it would be surprising if you could name a quarter of them.Ford was the first vice president to move to the post under the 25th amendment, which provides for a president to fill a vacancy in the vice presidency and for that nominee to be confirmed by a majority vote of both houses of Congress.
