i don't get this phrase, what does it mean?
the context is :
【The trip to Japan was Ford’s first foray abroad as president, and indeed, the first visit to Japan ever by a sitting president. Not having been elected to the office in his own right, he was being closely watched by the entire world to see how he would handle his new responsibilities. 】
as " in his own right" mean "by reason of one's own ability or ownership etc. ", didn't Ford win the election by his own ability? i don't get it
