The whole sport isnt biased against Ford. Ford would have to be an active participant as opposed to being a team sponsor for such a thing to happen.
They seem to have, by accident or design, put all their eggs in the FPR basket, and when there are holes in that basket (or feet..), there isnt another Ford team to be consistently competitive and up there with them.
That they get outpoliticked isnt a surprise either, because their motorsport manager seems to be doing it on a part time basis, does he even show up at race weekends?
Can he compete with the world's greatest wheelbarrow pusher in Mr McNamara?
The 'sport' didnt do any of these things, the Ford Motor Company did. Or didnt do, as the cause may be
