Why does the First Tenet of the Republican Party seem particularly questionable, in the 'light' of the current administration?

This could be a case of pride, blinding some from a reality that has evolved. Should we not read these words and readily be in agreence or is blind faith expected because we "choose to belong"? Is 9,8,7,6 etc., tenets agree with, out of 10 enough?

I am not affiliated with either 'party' and the lead-in posting secures why I do not subscribe to the two party system.
